really well done puzzle progression, i felt like the difficulty curve ramped up at just the right speed to keep things interesting without getting too hard, and i like the care that was put into introducing each mechanic. you can really tell a lot of care and polish was put into the player experience, from the vine changing color as you start to run out to the undo feature. the sound design is very pretty as well! the only issue i ran into was with pushing the rocks as some others mentioned, and the restart button in the top corner would sometimes take a while to do anything and sometimes not do anything at all. overall lovely concept and great atmosphere!
