I like this concept already, and of course there's room for improvement. I think there's lots of directions you guys could implement, personally imo I think a cool one would be to make it like a roguelite (like vampire survivors) where after some set score, the player will given the ability to choose between like 3 power ups that will help them. But I do understand if this is not the direction you guys want to go. Tutorials would be nice to have. Volume slider so you don't have to go all the extra steps to turn down the volume would be pretty nice.
