I loved it, the game was fun, music was pretty good, I wrote down a few issues though.
For one, the amount of enemies in some of the rooms is hard, especially with high-powered weapons. Also one thing i noticed is when you respawn in the pink room, an enemy immediately targets you, when you shoot more enemies follow, it can be a bit tricky to get out off. One more thing I noticed is that when you die, if you were shooting a weapon that is automatic, it will keep firing.
Overall really great game!
