Oh, thanks for telling me about the score screen bug, it'll be fixed in the next patch. Yeah a control rebinding menu is something I'd like to implement at some point, but it will probably take a while since custom maps is the next main feature I'm going to work on. Until I get that working, if there's a specific bind you'd like I can add it as an additional input myself so it will work as well as the current ones, as long as that button isn't used for something else
Edit: Fixed the bug now!
