All you have to do is 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. You can only do this a few times (up to five) per level, so you better watch your step. You can reset a level, but not undo the last move, which is a bit of a pain, though not really a big problem when the levels are this short. What is a big problem is that there are only sixteen levels, because Coloruid is one addictive game, and you'll be done with it long before you even begin to get bored. You may have seen similar puzzlers before, but what sets this one apart is the way the little squares wiggle when you interact with them. It makes their movement that much more organic, and it's fun to watch. However, the unpredictable movement patterns mean that a square or two might decide to go their own way and mess up the level setup, but this happens very rarely. The overall mechanics are simple, but wonderfully effective, and the difficulty increases ever so gently. This is not to say that you won't get a challenge out of it, on the contrary. It's just that Coloruid doesn't aspire to be overwhelming. It's more of a mellow, retro-style, relaxing-music sort of game that certainly deserves a more in-depth sequel. Let's hope it gets one soon.
