loved it! i REALLY like how you've managed to squeeze so much from one concept. a lot of other puzzlers i've played introduce new objects or mechanics when the main quirk of the game has nothing new left to explore/build upon, but the concept here has so much nuance (and potential!) that virtually nothing new was added that wasn't already there from the first level, and yet it still manages to stay interesting and fun to play. i think that says a lot about your skill with both concept design AND level design. really great stuff :D
