As a fan of both rhythm games and first person shooters this is right up my alley, presentation reminds me a bit of DOOM 3, I really dig it!
I had a great time, well done! :D
The visual style took inspiration from games of that era like the first F.E.A.R. and Doom 3, where I tried to have a mixture of harsh lighting and such. I'm glad the presentation works - it's definitely a unique vibe I was going for.
Thank you for playing!
