I suck at these kinds of games so I couldn’t finish it, but this is a neat idea! The loop theme is a bit of a stretch, but the standalone idea of a conveyor belt/factory themed Sokoban game is pretty cool.
There’s a bug where sometimes you walk onto the conveyor belt you’re trying to push. Might be a race condition? Also if the duck gets pushed into a crate by a conveyor, and then you push the conveyor, the duck seems to get stuck on the crate and you can’t push it.
