Hey, I sent this review to you on discord, but just wanted to post it for others to see too.
Your game was very short, but it did it's job. It works great as a small little minigame.
Art and sound design are minimal, but do their jobs. For gameplay, it took a few runs to figure everything out, but overall, it's fairly decent.
I don't have any criticisms about anything that was bad or wrong or anything, but I also can't point to anything that I found super amazing either. Overall, it felt decent, but not super amazing either. I wish I could point to specific areas, but I can't really find a ton of flaws with it. if anything, I'd do research into how to polish your games in general for the future, as I feel that's the only real advice I can give. screen shake, bass boosted sound effects for guns, etc. I'm just not sure what advice to give beyond that. overall though, you made a game quickly and you should be proud. great job!
