1) you having a ddr layout with arrows, the last time a game had that called itg, it got sued

2) your app needs an overhawl with how it looks, it looks like kiddies first app, as if you never made anything before and this is the first app you've ever made

3) I like the consept it just doesnt look good, sorry.

you talk about unity as if thats a good thing while its known by people that have used and tried including me that unity is terrible for rhytm games, because of the way the engine works its laggy and has slow responce when it comes to rhythm games, so if you want high end charts and focus on having hard core rythm gamers play it you're gonna have a hard time, if you focus on kids and have a fun gameplay you can make this prob a success, just my 2 cents
