Cool project! I liked the castle Wolfenstein style gameplay, and I did enjoy the mixed media for the enemy designs. The music was great! I liked the song, I found the bass to be a little overpowering in the sub range and would personally consider either turning down its volume or high passing around 30-60 HZ in order to stop it from competing with the kick drum.
I liked the shooting but didn't like the lack of audio feedback on the reload, especially since you can't reload with a partial clip. The second type of standard enemy seemed bugged in my run (they didn't aggro), and the game fully bugged out for me on the second floor, I shot everything in that room and was unable to deal any damage to the boss, but perhaps there was a mechanic i had missed. When I died the game crashed and froze at the start of level one with 100 bullets in the clip.
The shadows were also very janky.
Overall a very cool project and probably my favorite music so far!
