>>64702894The wall mobility looks pretty clean, and I've heard it can be a pain to get right. The part about incorporating fanart-ish things of chuubas is something I've been wondering about too, but I assume it's more trouble than it's worth if you're not making a straight up fangame. You can probably always do classic easter eggs. Good luck with the progress regardless.
I will try to use this as a motivator.
