I also wanted to note about the game's SFX, particularly the gun, being kinda limp and muted, making the whole experience less fun and engaging, but I hesitated to say that as I didn't want to come across as mean, and I didn't want to do a whole write-up explaining game feel in SFX, how it impacts the game, and how to change it, however I do think you'd really benefit from this classic 5 minute video that can explain it for me:
Right now the gunplay sounds and feels like that of Random Heroes, but with just a bit of tuning it could be so much more. This is all meant from a place of positive critical feedback, though I'm mildly autistic and I tend to come off as kind of a jerk over-text. I'm sorry about that if that's the case now.
