Super interesting concept. A new space invaders tied to rhythmical patterns, really interesting.

It is fairly difficult. I find it hard to remember what colors correspond with each tune. So when I need a red projectile, I feel like I'm struggling.  One fix I thought of would be to have each tune shown below but have 1 light up when it is in use.  Interesting game idea!

I liked the colour choose and concept, but controls are very confusing

Very unique, but it doesnt feel like you have much control over the game. Found myself just having to randomly change tunes.

interesting concept! i found it a bit difficult not knowing what signals i can choose from, so i was basically frantically changing them until it had a colour i needed.

Would be cool if you can see ahead and choose the tones required.

other then that, great work, i liked the minimalist aspect.
