The next version will add combo multipliers and possibly a delay. Originally you would lose points with each miss, but that seemed needlessly punishing.
Thanks! I'm glad you tried the android. I've been secretly playing every once and awhile XD
I am going to keep working on this! Final version should look something like this: http://prntscr.com/jwxvdm
Gamemodes are also going to be coming soon once I make all the game itself smoother and get the kinks out. If you are curious, I posted a devlog!
