My 2 cents real quick, mostly controls focused:
- Game needs controllers support. Fighting games on a keyboard are a pain.
- The dancing minigame: looks nice, plays "meh!" due to the DDR style. Harping on my previous point, a dual joystick gameplay ala Farenheit/Indigo Prophecy would really suit it but on RPGMaker that sounds like a pipedream. So my pro gamer move is to just mash the 4 arrow keys at the same time for the duration of the song on Hard and go home with 10K gold per dance and a case of the not-the-fun-kind-of carpal tunnel syndrome.
Best of luck dev!
