With wall jumps I feel it's either you love or hate them^^ But there are some really difficult ones in my game. I'm going to do a little update once the voting is finished to improve the balancing on some screens.
My initial idea was to let the player grad onto the wall so he doesn't fall down immediately, but I couldn't figure out how to do this quickly so I did dismiss this idea for the jam. Maybe I will have another look into it now without the pressure of the deadline.
