So it recently came to my attention that the Wall climber NPCs (Sparky, Zoomer, Spike Top) are bugged via
this google doc by
FanOfSMBX. It states that making these enemy's hitbox larger than the default 32x32 pixels will prevent them from making the turn shown on the right. _|
After seeing this, I thought, why not recreate these enemies using Lua, put then in the base game, and then deprecate the VB ones?
