Probably the most daunting task in the whole entire Level Editor is opening it. Don't worry, the buttons don't bite.

Whenever you start the game up on Steam, you have the option to change the Launch Options. You can choose The Impossible Game, which opens up the game, or access the Level Editor. And since this guide is all about the Level Editor, I think you can figure out what you need to click. Simply choose the Level Editor and click on Play. That will, instead of the Main Menu, open up a window in which you can edit, create, and upload your own levels, even with your own songs.

And that's the first step done, congratulations!

When you open up the Level Editor, you aren't introduced to any Tutorial screen, and any idea of a guide is thrown right out the window. Why? Well, because it's all pretty understandable by itself in nature!

In this step, I'm gonna go through and explain what all the buttons at the top of the window do.

This button allows you to create a completely new level with nothing in it. Be careful, because the game does NOT ask you to save the level before creating a new one, and you can lose all your progress.

This is used to open your levels, and any other levels made by others. It opens up this similar looking window in which you can choose a folder of a level. When you find what level you want to play, simply choose the folder and click on Select directory. The folder contains 2 files: level.dat and music.mp3. The level data file contains all the data of the level that the game recognizes and loads up in the Editor, and the music file is played over the level.


Fun fact: There are 2 secret levels you can play in the Editor. Open up the "editor" folder, then the "levels" folder and choose one of the 2 levels sitting there. They're fun!

Open Audio searches for .mp3/.ogg files as the song of the level. Pretty self-explanatory. You can find the Main Game songs in the "res" folder, along with the Menu track and the Practice Mode track.

This saves the level, duh! :o

If you have already chosen your music for the level (which is probably generally the first step you should always do when you open the Editor up), it makes a folder with the level data and music files inside it. You can then use it to load it with the Open button.

This opens the game and plays the level, so you can properly playtest it yourself!

The next set of buttons are grid-related. As you can see, the whole editor is just one big grid where you can place objects. Each object takes up one space of the grid, and there's no object limit.

Self-explanatory. Just toggles on or off the grid.

This option is turned on by default. It snaps all the objects you place to the grid, therefore being nicely next to each other without any issues. But if you, for some reason or another, want to do something else than just a standard level, you can place your objects off the grid. Please mind that the objects cannot be stacked on each other and have to be at least 1 block next to each other in order for them to be placed. You can use this option to make some art, like a heart for some reason. Just like I tried making a heart for everyone who still plays this game, and is enjoying this guide!

This is where we get to actually building the levels. There are 7 options in this tab, each filling up a specific role in making your level good. So let's explain them, shall we?

Before we actually get into it, though, you can notice a red border on the beginning of the level - and whatever you do, make a new one, delete it or something, it ALWAYS stays there. Why? That's the beginning of the level, the fade-in. You cannot build blocks and change backgrounds in it,

The standard, almighty block. The only thing you can land on that won't kill you. The savior of all our lives. THE GOD. Place it anywhere you want and it'll look nice.

A spike that will kill you when you touch it. Looks especially nice when you put it on a block.

The pit object is basically a spike, but on the ground. It looks better than placing spikes all over the ground. Also, when you hold and extend an area with the Pit object selected, it covers that whole area's ground by the pit. I strongly recommend using Grid Snapping on this one, but it's not required. Such extended Pits are deleted whole, not just one block at a time.

Used to, well, delete objects. Not really needed because you can delete anything you want with your right mouse button, but it's there for anyone who likes to click buttons or might not know about the keybinds.

I tried searching everywhere for this, but it only really serves as a music-related thing than anything else and isn't a part of the actual level. Refer to Editor Buttons: Music for more information.

Place it on the tile where you want your level to end. Note that the level end, as seen in the Main Levels, is the square icon automatically jumping up. You can make it nicely connected to the end of your own level.

Background changes are the second hardest thing right after opening the Editor up. To use it, choose the color you want your level to change into, and then click on the "Place Background" button and click on any grid space. It will change the color of your level! It also slowly fades into the color when you're playing, and here's how it looks in the editor:

Nothing special for these 2 buttons, as one of them has already been explained in the previous section of the guide, and the other one being pretty self-explanatory.

This option deletes the mark you placed with the "Place Mark" option.

An option to change the background color of your level.

The last 3 options of the Level Editor are related to the music playing in your level.

Rewinds the music to the beginning and plays from there along with a line that tells you where the player is going to be at what section of the music. It's going to start playing from a mark if there's one placed in the level.

Plays the music from the mark, if there's one placed in the level.

Plays the music from the beginning, regardless of any marks placed in the level.

The Jump Guide is pretty much everything you would expect. By pressing Ctrl on your keyboard and your Left Mouse Button (LMB), you can see where the player is going to end up when jumping. You cannot turn it off unless you restart the Level Editor itself, so if having 4 curvy lines around in your level is not your thing, that's okay.

The Level Slider is at the bottom of the window, and you use it to move around in your level. You can also move by larger bits with your left and right arrows.

Thank you for taking some time of your day to read this, and I hope I've been helpful to you and your journey of awesomeness! I don't usually write guides, so it will by no means be perfect. It will be updated frequently with suggestions of other people in the comments, and I'll also try to sort out typos if there are any.

I will respond to all suggestions and criticism, usually within 48 hours, and will answer any additional questions you may have, change any errors you've spotted, or add something to the guide itself. Also, I had a little plan of making a simple website to host custom levels, so tell me if that would be a good idea. While you're at it, please rate the guide! I appreciate the feedback!

So now, player, it's up to you. Good luck building your levels! I hope to see some of them later down the line.
