Visually the game looks really nice, and the sound effects are great too. The Buckshot Roulette inspiration is obvious, which made me notice a few differences while playing.
I think it's missing a bit of balance. This is probably something other people have already mentioned, but I think it's true, especially when it comes to the pills.
Another thing a lot of people mention is the audio, but I honestly think that's just a "ran out of time" kind of thing, so I wouldn't worry too much about it.
The biggest thing I'd personally change is adding more game juice. More screen shake, particles, and little impact effects would make the gameplay feel much more satisfying and dopamine-hitting.
Overall though, I had a really fun time playing it! Great job, and I hope the feedback helps.
