I liked music and MC concept arts. Firstly I want to say that there is things to work on character movement. Your programmer have used some platform-movement features and this is cool! But not all of them and because of it there is some gameplay issues.
And what about idea. Changing keybinds - this is something bold. But this gamedesign idea have a really BIG mistake - you by your own hands forcing your player to break his immersion in game. Instead of being engaged in the game world, I have to stop playing., look at my keyboard and press one by one to find some. This is hurt my experience and will hurt other player too.
I think you guys have some cool ideas, and with more polish and iteration, they can become much more engaging.Keep up the good work — you're on the right path, just needs more refinement!
