In case anyone doesn't have time to look around, here's a quick guide to find all collectibles for manor_of_mischief. (https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2578001777)

By collecting all gifts, you will unlock spells, which will appear all across the manor and exterior.

By collecting all the headcrabs, you will unlock the secret door at spawn, leading you into a developer room, full of art, development pictures and memes by me!

Here is how, and where to find them:

Headcrab #1

Right outside of spawn, on the roof awning above the manor entrance, hidden in the dark

Headcrab #2
Complete the box jumping puzzle (Or just rocket jump up, whatever works!)

Headcrab #3
In the flipped room, next to the box room, on top of the bookshelves, again you can jump up, or use other means to reach it.

Headcrab #4
On top of one of the toxic waste barrels, next to the radioactive slime pit (Don't get irradiated!)

Headcrab #5
You must first step on the mouse trap, to enter the mouse hole. The headcrab is located on top of the big "cheese" Make sure to enter with some extra health, or you will die on entering!

Headcrab #6
Go down the dark staircase, which leads into a glowing white door, once in hell, take a hard right down the small path, which leads to a hidden little area behind the rock, including a little headcrab!

Gift location #1
Easy to find, simply walk into the graveyard once out of spawn

Gift location #2
Once out of spawn, head left, and walk into the forest, keep walking until you come by a small awning roof, jump up and grab the gift on top (may require

Gift location #3
Continuing along the forest path, head through the medieval town, and past the toxic slime pit, you should see on your left, a fridge in the ground, close by to it is a gift.

Gift location #4
Return to the forest path, and head towards the big mansion, once inside the mansion, jump across the flying islands until you reach the end. You'll have to make a leap of faith for the gift, hanging by the chain!

Gift location #5
This time, head down the right hallway in the main manor, until you reach the dark staircase, leading to hell. Once in hell, complete the obstacle course, and jump into the skulls mouth to collect the gift in it. (This will probably kill you!)

Congrats, spells should now be enabled all across the manor! Enjoy.
