I really like the cube dropping mechanic, I think it was the highlight of the game. Blocking enemies and making platforms was something somewhat new and innovative, and with some polish and level design focused on that, you could make a very special game! The shooting felt great, each shot looked very good but the enemies took so long to be killed the the shots felt weak (also I can't fire the laser I see on the screenshots for some reason?). I also think the controls felt a bit unwieldy because we couldn't do short hops, and we were forced to move if we wanted to shoot diagonally. I think that basically you have a good foundation of a game, it just needs more polishing. Great job!
