Yo, I really enjoyed this! Great work!
I have some minor critiques here and there; stuff like certain weapons being... well, Not Good (the shotgun 💀) and occasionally not being able to aim as high or as low as necessary to hit some targets, as well as the levels being a bit too... sprawling, I guess, but overall there's a lot here that's great. The sorta PS1/Early 2000s PC game aesthetic is really wonderful, and the overall feel of the game (i.e, movement speed, how the guns handle, etc) feels great. You did great, thank you for making this!
