This is such a vibe. I absolutely love how well the environmental rhythm has been incoroprated in this game. Also the visuals are stunning. The only thing I dislike is the visual clarity on some of the attacks. For example the droplets on each level are very hard to spot. And the indicators, especially on the very first spike attack in the first level are insanely hard to distinguish while dodging something else. Additionally, I feel like a double jump instead of the wall jump would've been more intuitive. Also, a life bar please :x
All in all, a great experience, good job!
Edit: Also noticed that some things keep dealing damage after they're basically gone from the screen already, and that the deafener doesn't work on area effects
Edit 2: I succesfully got the glowstick :P
