Oh, solid game! Honestly, I found the gameplay pretty satisfying. Moving around, shooting, enemy movement, etc. all felt smooth. Also, the gameplay logic reminded me of Enter the Gungeon, and I really like that style. Not sure if it's just me, but sometimes I couldn't tell where to go — maybe adding a minimap or something similar could help with that. Other than that, when a lot of health pickups drop and you grab them quickly, it seems to trigger a really loud health pickup sound.
Great game! Keep it up!
