I really like the idea! I would love to play a sort of rpg/tamagotchi crossover thing like that. I'm actually lowkey jealous, I'd love to make a game like that. Idk if that can help but when giving a potion to the knight (like dragging it on him without him going to the potion themselves) and then drop an enemy, the game glitches then crashes. The debugger said it was a failure to switch states I think. Anyway, hope you will come back to it!
