Okay, so this is just some boring* minigame which won't last you longer than 2 minutes (unless you like trying to beat yourself over and over again at some thing.)
Move your rainbow ball with arrows, avoid grey fireballs from evil grey cannons that look like scouges.
There's a bit more tho: if you step on a tile you colour it, colour tiles to get points. You can press space while moving to make yourself a flying ghost... or something. Just try it. You'll see the advantage. Also, the top cannon may launch a red ball sometimes, get it and all bullets on screen disappear and you win +100 points.
