I'm trying to figure out new keybinds, but everything I try really doesn't fit right. I'd like your guys opinions on the best keybinds for this game. secondly, I'm struggling to get past the hello kitty boss. I have been able to get her down to around half ish HP, but no farther than that, and I can't really do that anymore. any tips on how to make the boss easier?

Hello, I recommend you watch Tyste's videos, and regarding key configuration, I use ESAD to move, W to jump, spacebar to shoot and R to reset, I have also used spacebar to jump, M to shoot and N to reset, I recommend you keep testing until you find what you find comfortable.

Impossible to answer without accounting for your subjective preferences, but there are certain rules that I think help like not using your mashing hand for jumping. For example, BBF jumps with the spacebar and shoots with E. This would make zero logical sense to most runners without significant habit-adjusting.

Another example, LogicPQ, the Guy WR holder uses space for jumping, but moves using WASD and not arrows. He shoots with his right hand, but moves the hand away from the shoot key to do the jumping for the platforming. His assumingly dominant hand is used for precision jumps that way, and when he has to fight the bosses, the left hand does the jumping and the right hand is focused completely on shooting. This clever use of the spacebar turns it effectively into two jump buttons.
