Very cool controller!
About the character: I like his face and animations, but the clothes make him too generic without any appeal, so you may add cool clothes and hair customization options, it will be easy for your lowpoly style
My plan is to add the ability to change his shirt and pants color to whatever you, the player, want, as well as to add a scarf. The scarf will be cool because it will replace the bat (you'll spin and hurt people with your scarf as opposed to the bat) but it'll ALSO be an indicator for your trajectory when you're going fast (it'll replace the blue beam of light thing that I currently have for that same job). Thanks for playing!
