Hehe, Wolfenstein vibes!
As @Philip mentioned below, I also missed being able to jump. And it took me a while to figure out how to use grenades because I completely missed the top bar.
Also, enemies can shoot through barriers? That's not fair! :D
Was everything made with Claude Code, or did you use any other tools?
Btw, have you tried my game? Would love to hear your feedback too, if you get a chance! :)
