FFFFFF-

This is a game that was very much inspired by the game VVVVVV.

Instructions

W / Space = Jump
A = Move left
D = Move right
S = Crouch
E = Use (Only works on the portal when it's activated)
And some more keys that i'd rather not spoil, the game will tell you these keys when it's time.

The game does have custom levels implemented, but it might be a bit complicated for some due to the way it loads levels.

First of all, to make a custom level you need to go to the folder with the game, and then into the "levels" folder. Here you need to create 3 files, and they have to be named properly like this:
<levelname>.png
<levelname>ents.png
<levelname>back.png

replace <levelname> with the name of your level.

<levelname>.png handles normal tiles that you collide with.
<levelname>ents.png handles entities.
<levelname>back.png handles the background tiles.

Each color on these images represents a different tile or entity, you can find the list right here:

It might look a bit complicated for some, but i'll try to explain it. On the spikes, the Blue value in the color represents the rotation. 75 is 90 degrees, and 225 is 270 degrees.

On the lasers however, x represents how far the laser will go. This is calculated by multiplying the length you want the laser to go by 10. Horizontal lasers always go to the right when added. Vertical lasers always goes down when added.
The y value represents the bounds of the laser. 230 is 2 blocks, 240 is 3 blocks and so on.

The elevator is the same as the lasers.

I hope you understand all of this! Have fun!
