Whew, I thought I wasn’t going to make it.
But here it is, ColouredWorlds !
(if you use MacOS or linux, you will need LOVE, you can get it at love2d.org)
Use the power of the coloured worlds to make it through the 10 levels !
I used Lua, LÖVE and Sublime Text 2 for programming, the GIMP and Inkscape for graphics, and MuseScore for the music.
I’d be very pleased if you gave it a try !
