This is a video uploaded by Venturiantale https://www.youtube.com/user/VenturianTale
It shows the tutorial and the start of the game it is 30min long and helped me decide whether this was worth the price which it was and I am glad I got it. You can see the use of fireworks as well in it

Do not read if you think these could be spoilers.





At the start of the game you are told by Mystery Box that GPS [Global Postal Service] is in trouble and is basically creating a smart box to help them. [you]

From there you find yourself being spawned and meeting the first few characters and doing tutorials then from there heading to the Paradise Isles.
If you go to far from the area you are supposed to be in you are respawned this goes for challenges as well.

The abilties you have access to from the start along with offensive weapons

Unbox- A powerful double jump you can have 6 of them at max health perfect for getting from place to place and between Islands easy. Some challenges do not let you use Unbox and some you need it to reach the target.
Slam- Stun enemies and push items like rocks away. Use it to fall faster after a Unbox or jump off a high ledge keep in mind you lose all movement control while falling with slam so once you start you won't be able to roll forward much unless you cancel it. You can also use it to activate buttons
Jump- Normal jump no health needed
Fireworks: You get these in challenges and boss fights they lock on to targets and get rid of them instantly the Parcel Peaks boss fight uses these. When its red on the target it may not hit as it is being blocked when green fire it will hit unless something gets in the way, like a car.
Roll- You passively do this as it is the form of movement
Defense Abilities-
Unbox- Double Jump can get you out of fights with Blue boxes which Slam does not stun also escape fights you can't handle with low health like when a Wild Card locks onto you with a firework.
Slam- If its a blue box try to push it off a cliff with Slam or into water. Stun Wild Cards that come at you.
Offensive Abilities-
Slam- Stun any enemies that attack you instantly getting them out of the fight.
Fireworks- Lock onto targets and get rid of them with these keep in mind when they hit you as well they apply a effect like a bunch of balloons.
Movement-
Unbox- Get to high places or transverse the terrain fast
Jump
Roll
Slam- Fall fast to a destination from high up
Certain effects from Fireworks that hit you, I use the balloon effect to get to a place sometimes.

During Boss fights you always respawn
The 4 maps are in this order:
Other Base
Paradise Isles
Parcel Peaks
Isla Cartulina

Other Base- The midpoint between worlds you go there with F at a Checkpoint and in the Pause Menu. Each map has a crate you jump into to get to that map. Parcel Peaks is on the middle of the Oil Rig that is Other Base, Paradise Isles is near a boat below a elevator and Isla is up a orange elevator on a Helipad with a active Helicopter. You must earn the Master Stamp by defeating the boss in each map excluding Other Base. The places where collectibles are hidden are on Buoys, rooms accessed by switches and on high areas. Also there are 2 large Buoys leading out to a path of health packs that give 6 each its a lot of travel that leads to some golden tape almost every buoy here has a Tape on it these ones are behind the runway behind the hole near a smaller one.

Paradise Isles- A colorful paradise with multiple islands connected by bridges and crates to jump across in the middle is a giant radio tower. You will not encounter Gtape if any at all in caves as there doesn't seem to be any. The most deadly thing here is the water if you fall in it twice without touching land after one fall in you will die, you are a cardboard box after all. When you first arrive you are at a dock where you will do a challenge issued by a Zippie that has you practice Agility in a infinite time race then Firework shooting then a small easy puzzle in a cage where you slam a button. After that you follow along a road eventually finding Bounce's home there where you can learn the controls again or get general screenshots of Tape, Stamp, Trapped Zippie locations of the areas they are in you can keep asking to get more or the same screenshot if it happens to be the last of them. That saved me on the last tape on the final map. There are power lines you turn on in a challenge given by a character that are connected to each island to power the radio tower except a small island off the coast of where you find Splash. The Boss Fight here requires 10 Stamps and takes place on the top of a edited Radio tower with no antenna where you must push the enemy off the ledge 3 times to win. If I forgot anything let me know and I will add it. After the Boss Fight you end up in Parcel Peaks and can return to hub to go back to this map.

Parcel Peaks-
A few Snowy Mountains with ice that you can roll on for speed boosts or Ski on. The Terrain is icy tall and has a Spiral Mountain that is also a challenge at the top is a little Golden Tape about 3 of them. There are caves as well with things to find in them sometimes Zippies that are trapped. You start around Bounces place in here and can get screenshots of items again. Most of the characters here are wearing cold clothing and complain about the cold. There are broken Cable Car Systems you can unbox on to get to places or Unbox across short broken bridges there are also car tunnels and roads. The Boss Fight here is a Helicopter that fires all sorts of nasty Fireworks and is to me the hardest one the Fireworks will kill you fast so get to cover with a Weapon box nearby to fire back you can also intercept some of the Fireworks with one of yours. Let me know if I missed anything. The boss fight here takes 12 Stamps

Isla Cartulina-
This one is not in Islands at all but is all connected it has a Volcano with water in it which is deadly to you since you are a box there are numerous underground caves and lots of Tape in them you will have a lot of trouble finding everything on this one the boss fight is also a Laser Throne Statue. You use Fireworks on its eyes to win this one and the laser kills you instantly regardless of health this is the final battle as of now. Its a terrain you can access pretty well with a car since its mainly on a path. There is tape basically everywhere on top of mountains when you first spawn and underground or in rooms with boarded up windows which you can acess with caves behind or below or by falling into some. There are more traps than any ever map: Spikes, Fire, and face blocks that push you down or crush you. The fans here are made of Stone. Let me know if I missed anything. There is also a Jurassic Park looking door that leads to Bounces place. The boss fight here takes 14 Stamps.

There are fans that can send you various distances they are a joy to use but you may need to roll or Unbox to the destination as well. There a rusty Grates you step on to make them fall to get stuff as well as automatic items that collapse underneath you when you step on them or swing away. You turn some on with switches that can found in various spots some of these switches have timers but thats mainly for other stuff. Let me know if I missed anything. There is also a clothes shop in every map and multiple in Parcels Peaks with a Pink/Purple Box on it in each village you unlock itemsc there by finding all the stuff in the maps.

Items you collect that add up to the completion of the game and unlock Cosmetic items at Swift Tailoring
There are also Checkpoints that refill health to max and allow you to respawn yourself to them whenever in a pickle. They take the form of red mailboxes and blue ones in challenges.
The things you collect
Stamps: There are 18 in every map but Other Base which has none.
Master Stamp: 1 in each map which unlocks the next map and is gained after a Boss Fight none in Other Base.
Trapped Zippies: 10 in each map excluding Other Base which has one.
Golden Tape: 200 in each map in certain maps can be in caves.
NPCS: These characters are the ones you get a Stamp from by completing the challenge. They can be found at certain points like Superbox is always at a Village that is under attack by Wild Cards.

You can also find Mystery Diaries that give info on a Alien that is currently on Earth these are the only things I haven't finished finding but they do not count towards game progress just are fun to hear. No Spoilers ;3

The enemies in this game are called Wild Cards and one is called Boss Wild who is in each boss fight.
These enemies have based their gang off biker shows from the 50's. They listen to Rock Music in speakers that you can see and hear. They can keep spawning at you if there is a Box A Matic.

2 Wild Card Types:

Normal ones: Found in all the maps except Other Base and are the only enemy other than Boss Wild that are in Paradise Isles.
Blue Ones: These ones jump and explode on you it doesn't deal damage but can send you far away into a trap or water. They can't be slammed to stun them.
Special ones:
GPS Helicopter: Only appears twice as a enemy you fight. The Parcel Peaks Boss Fight and the Village defense challenge issued by Superbox in the last map.
Boss Wild: The boss fight in Paradise Isles he appears as a giant box with scars on him
A statue with Lasers: Appears in the final boss fight and in Isla Cartulina.

Slamming the normal ones immediately gets rid of them

I will add more to it as I remember and then start putting the locations of characters in in a couple days. You can access to a objectives/locations marker that should lead you to them.
