Was fighting the Arch-Villager, died about a few times, but when i eventually got him i was using the Pistons at the same time, it basically got me stuck and nothing seems to work, meaning i have to redo the ENTIRE level. I did spend a long time into this one, defeating every enemy and attempting to uncover every Area, so its quiet frustrating for me.

As a suggestion: Maybe add a ''Reset'' button for issues like these, so if it happens we can just Reset ourselves again without being stuck.
To avoid to abuse the Feature (if that should be an issue for some reason), maybe with a cooldown and/or at the cost of half of the current life.

UPDATE: It seems that i managed to free myself, idk how or why, i tried the same thing all over
All i did was moving my mouse and clicking, and after some time i got free. Thought by free i mean fell into the cliff, so it did took damage, and for others who are low on health might be a Game over
