Thank you very much. :)
I'm curious as to which places you got stuck on, as the mechanics (and the positioning of the sensors) should allow for the player to undo the actions they did. There have been a few situations in the past where the player could get themselves permanently stuck, but I think I fixed those.
I am wondering if you didn't know that you could pickup and drop objects, like my friend did. I probably should have at least put some text in-game to help with that.
There is a bit of a problem with resetting the position of objects is that some of the levels rely on objects' positions being saved, though it is doable. Though I'm pretty low on space in Pico-8.
Allowing the player to pull objects towards them would definitely allow the player to get themselves stuck though.
