Not to sound flippant, but just… don’t spam potions. Wait for the animations to finish. This has always been a thing.
It IS jank. It’s an extra feature mode in a $3 game made by one dude (should have made it $6, but still). And with the massive list of transformations, not everything is compatible, and i will definitely break something in the main game if i start adding restrictions.
Glad you are enjoying regardless!
