There's a lot going on in this game, to the extent that it can feel overwhelming at first. But I'm so glad I stuck with it after my first couple of runs ended almost immediately. It took me a while to wrap my head around this one, but the strategy that started to work for me was focusing on only a single color at a time, getting its bar full and then clearing that color completely and moving on to the next color for a while. Trying to bounce around between colors just led to despair :) Things still don't last terribly long, but you can get into a bit of a rhythm (I was able to bring the reactor down from critical 7 or 8 times before the explosion on my last run.
The music and graphics are pristine here, too. Everything is super clean and smooth, and I particularly love the death animation; making the death animation so slick (both visually and aurally) is one of those things that makes it easy to start another run instead of giving up. It's so neat seeing the greyed-out shapes slowly slide away into the world, and hearing the music wind down. The little auditory flourishes really add a lot to the atmosphere.
Super slick game, and I really enjoyed the time I spent with it. Awesome work!
