The enemies need to be a bit more visible but other than that, this is a solid entry. The controls are really smooth and easy to take up. Good job!

Pretty awesome little game! It can be improved with very simple tweaks and I hope you update it.
Mostly you might need to work on the visual hierarchy - make the most important things for the player bigger and easily visible.
I think the loud music and the transparent timer in the middle were very distracting. The border could also be smaller since it's not a part of the gameplay. The enemies and projectiles are a very similar color to the background elements. Either remove the background or make them more easily recognizable. I know you're going for the 1 bit aesthetic but it would be cool if the enemies, or enemy projectiles are in color, for example.
Overall - very fun and with lots of potential! Good job!

Very fun game overall, I loved the concept and the enemy types. I also think the auto-aiming does a great job of keeping the player's focus on the controllable character's movement. More of a suggestion than a criticism, but since your game is centered around the pulse of the player's movement, I think it would be cool if the music's tempo was synced with the player's pulse. Great work!
