Cool game design! It is a bit hard at the beginning, but I got better really quickly. Maybe you could add a high score mechanic and some more "juice"? Just a few more indicators and stats, like in a classic arcade game! :D
I didn't know you could even add a high score until I played your game (speaking of, really cool) and I have no idea how to do it, bit I'll try for sure! I plan on making the stage more lively the higher your combo in the future.
