I have to chime in in agreement that I wish the physics were a bit more stable - I appreciate the reset button to help out there, but the number of rooms i Had to reset just 'cause something had gotten stuck in something else was very draining. Escorting the star ball through the multiple rooms is a really clever setpiece that I wish was as fun as it deserved to be instead of frustrating.
I also had an issue where I accidentally rotated myself out of the magnetism room after unlocking the upgrade, and so didn't get to read the instructional text 'cause it disappeared when I left. However I also never really worked out what magnetism was for, so...?
BUT importantly it was cute and fun. I felt very lost at first but when the core mechanic started clicking it really clicked, and I had a great time with it. It's a shame that the buggy physics made the final stretch kinda put a damper on that 'cause with the kinks worked out I think it'd be a real fun lil experience with a lot of potential for a variety of puzzles.
