Thanks for playing, glad you enjoyed the presentation! I just covered the softlock in a devlog. Pretty much what happens is when you apply a state to an enemy who is immune to it, they lose the state. This breaks battles because it checks if the enemy has the state at the end of each turn to advance the puzzle and you can no longer apply that state. Pretty pissed I never noticed that while making the game but I'll definitely address it in Definitive.
