I had such a fun time on this - movement felt satisfying, the gun felt satisfying, I enjoyed exploring and backtracking around, and I'm a big fan of the overall aesthetic and vibes. The couple bugs I ran into (namely the known crashing bug and a few instances of clipping through geometry) were a bit of a nuisance, but not enough to really detract from the overall experience.
There's definitely polish to be done, but it's already shining a lot imo!
