Relaxing & cool game! Some pretty engaging puzzle design here - all the toggles you've added for accessibility are welcome too. The only thing I'd recommend is lengthening the amount of time it takes to confirm an input - the undo button was a great addition for this, but I think the register time for movement/pushing boxes could be slightly different to circumvent erroneous inputs (maybe toggleable?). But with the constraints of a gamejam, it'd be hard to tackle something like this addition in time, so great job regardless!
