It's an awesome game concept!
Me and my bf enjoyed playing with it, too bad it doesn't have online multiplayer :') If ever you're thinkin of adding of multiplayer, PLEASE make it online with code invites! It'd be way more fun to have more instruments and play with many friends (Suggesting maybe add 2-6 player or 4 player at least) with optional instruments! We'd be jammin to this for HOURS if that happens ^^ Waiting on updates!
