First off: There is an error popping up when trying to play full screen.
About the game: It's a simple concept but it does have a bit of a Guitar Hero feel to it especially since it uses a lot of the same colors. I could see this working on mobile with some tweaks. As is the difficulty ramps up too slow in my opinion. I got a bit bored at the start and it took quite some time to get to the challenging part which was way more fun than the start, so make sure you get there sooner!
I think I did quite well ;P
Congrats on finishing your game for the jam!
