"Instantly playable" and "instantly enjoyable" are 2 phrases I've come to expect with Bart Bonte games. Simple and fun games, easy to pick up and play. This one reminded me of Eko's H2O for the Atari Falcon and DOS PC (which in turn sort of reminded me of Lemmings) i.e. try to pour particles into designated areas by drawing walls, etc. I haven't finished it yet, but there are a few twists in the original gameplay, but I expect well thought out stuff as usual. Dig in!
