Great game with lot's of enemy variety! Really impressive! I reached level 20 and there seem to be some bug as the boss isn't spawning. The level 10 boss seem to be stuck too with it's projectile unable to reach me (attached image), not sure if that's supposed to be the behavior.
The game is really fast paced too and there's this drone that is really hard to deal with that follows the player all around. Anw really great job and this has lot's of potential!!
