There is an attack speed, movement speed and jump height boost on landing a perfect hit, so it's not the wyrm messing with ya! You just have a keen eye for small mechanics like that.
This boost can also stack to crazy amounts : )
read this comment and decided to perfect hit checkpoints a million times in a row to get huge jump height, turns out you can jump right to the end of the final level to grab the key lol
i was really hoping there'd be something at the top of the level 2 secret checkpoint building.. i worked so hard to get up there!!
cool game btw c:
