This was fun!
I enjoyed all the puzzles, though sometimes the movement speed felt somewhat slow. It felt great in the earlier levels, but when the levels became larger and harder (more resets) the slowness started to become noticeable for me.
Very minor thing - it’d be great if you could hold down the push/pull button and walk into a crate to grab it. Sometimes I would press the button slightly too early and it wouldn’t grab because I wasn’t close enough yet. Maybe I’m just impatient 😅
I love how the 10th level felt like a combination of all the mechanics learned in earlier levels, but still required some brainpower to put them together in the right order, it was a nice way of ending the demo.
Good luck with the full version, this is a great concept!
