Nice take on a classic game, the combination of puzzle and shooter works well, and it gets more and more complex as you move along, with a larger set of colors as well. After a while it seems like the difficulty level is fixed, but it's still hard enough to not be endless, and getting the score up is a challenge when it keeps going down if you don't shoot something. That latter part is a bit of a shame, since it would be nice to take a break from the shooting for a second or two to avoid moving blocks and stuff, but nevertheless, it's a fun game, and a challenge. Nice work!
