Completed the game. Very solid entry, interesting weapon designs, i like how you charge back your health through enemies corpses to ascend again. A bit too difficult on one or two rooms, but a very enjoyable experience overall. Good ambience.
Did i saw a goatse reference on map 2 or that was just me seeing things where i shouldn't XD
Easily readable pickups, that's a good one.
There were moments where I thought projectiles were going to hit a wall, but i guess projectiles have small radius, so they hit me anyway, very good weapon sound effects.
Smooth framerate, that's a bonus :p
Good stuff.
