Wait, what's the issue with the config, couldn't you just rebind? Menus are quite iffy across the board though sorry about that one, will definitely fix that down the line.
Please don't worry about me too much, I'm just one of those bad-behaved impatient players who aren't willing to think about what controls they *might* need in the game before having tried the game first. *shrug*. I'm guessing that people who are actually SHMUP fans might be more willing to prepare?...
I was able to rebind ESC back if that's what you mean. It's just that I was so unprepared to not be in a main menu but instead be forced into a config screen that I mashed buttons hoping to just get to the game asap
