Very nice start! The visuals are great and the mechanics you have implemented so far feel nice. I liked the menus as well. Only complaint I can give is that I can imagine playing two player would get real cramped on the keyboard, and in the character select/stage select pages, it was a bit jarring when I was selecting my character or the map with the keyboard, but then had to switch to mouse to make the confirmation at the end. But other than that very well done!
Thanks for the feedback, yeah not having controller support was a bummer to be sure. I wanted to add controller support but Unity's input system has a really odd way of implementing multiple controllers. It ended up eating too much of my development time. It is something I really want to implement in a future update tho.
I hear ya on the character select screen, I'll have to update with mouse controls.
