thank you! glad you enjoyed the puzzles
as for the undo functionality I was mostly afraid of having players end up brute forcing the levels instead of pre-planning and thinking about the box's trajectory and the movements each block can do etc etc, which would destroy the whole puzzle aspect since there are technically very few paths to take, as opposed to say baba is you or something similar where the undo button still doesn't allow brute forcing
I do understand there's clarity problems with the buttons tho for sure, thanks for the feedback!
