Very cool idea!
It's actually more challenging than it looks, sometimes the wave doesn't cover it all, even at max frequency and amplitude, especially since you run out quickly of energy.
Also I think I shouldn't play before my morning coffee, took me 2 games to understand that these weren't buttons on the right side but indications of what to do on the keyboard, I was clicking them like crazy and wondering why nothing happened 😂
Graphics are minimalist but quite polished, all fits well together.
Would love to see where this goes!
