I'm not sure to be honest. Usually puzzle games have a level that is just designed to teach you a mechanic. If you make a level like the fist one where you need a step stool to get to a higher area and the respawn is close to that but it cannot be reached by just leaving the pumpkin on the floor, I think it would suffice. You also should add some sort of effect like a magical particle floor to pumpkins in the air like that because without it, a player like me might think that it's a bug.
