the game is great and has so much potential but i have a ftwo suggestions
1: instead of turning the slime-naga-shadow thingy into a copy of shiriou, make it able to transfor into the others heros or at lets tunr him into a big booty slime-naga thing
2:the UI is good but plai grey is not my fav color (or anyones) and i would love to make it able to change its color in the menu
