Stairs the game! Haha jk very fun game I sunk a good chunk of time playing it! Puzzles were challenging but not too difficult and fun. The difficulty progression felt just right as well I never felt like one puzzle was a sudden jump in difficulty.
Not so much a critique but a suggestion for a similar future game, it would be cool to collect hammers and switch between editing and playing the level somehow! Would add a bit more variety and possibly add more interesting puzzles!
