Amazing Game this feels like way more than a fan game absolutely loved the characters and their designe can't wait to see more of them.
Here's some positive feedback if it can help:

-The warning starting screen should probably be skipable it takes alot of time to get to the loading screen.

-Maybe add some characters infos in the menu with 16+ characters this will be helpful to remember everybody.

-Adding some option to changes keys would be nice.

-This game is inspired by the dangan games but you guys have far passed this step, don't hesitate to add any crazy new idea to the mix.
