Very good entry, the global art direction is very nice, and the core gameplay works very well! I just found that the projectiles were a bit too slow, and that the game take a little bit too much time to get harder (I started to feel that the game began to be harder around the 60th enemy, would have liked to see a swarm of angels and demons a bit sooner :D ) but that's not a big problem at all or anything.
You all did a pretty solid job, congrats to the team :)
