Play Coloruid in FULL SCREEN
Little puzzle game where the goal is to turn all the squares the same colour in a limited number of moves.
Click on one of the squares at the bottom of the screen to pick a colour, then click on one of the groups of squares to paint over them.
Same! The music is very similar to the music of Dwarf Fortress.
It's quite like flood fill. Actually found the music the best part of the game.
