This is really impressive! I love the aesthetic and the controls are good! I think adding some sound effects for hitting the enemies and shooting would've gone a long way, but still, making this type of game in a week is awesome!

Reminded me of very good times in my life. Those DOS games and the early 3d era. Great work. Visuals and the level design are so unique. Also the graphic quality choice makes it even more special.

This was great. Love the throwback style, like doom and wolfenstein. Mouse was a tad sensitive. But not a big deal. That you managed it by the deadline is crazy. Good show!

Really enjoyed the game! 3D was a pleasant surprise, the level design was on point and the music+art combo was perfect, thanks for the experience <3
