Make a game for fun

I Have been developing a game of my OCs, is a rhythm game with combat as the main mechanic in a semi-open world

I wanted to make a game inspired of a other game like honkai impact 3 and my likings for fun

Is still in concept because I’m still deciding what my OCs should look like in the game and what special abilities I should give them
One of them is a little bean demon which I’m still thinking of what ability to give him
