Cute story, clever puzzles! I was honestly stumped for a minute with the flowers puzzle until I figured the trick out. The ending was a little too straightforward mechanically (story-wise it was fine) with choice events that didn't seem to be necessary and movement that wasn't terribly meaningful.
Overall the game is not too long nor too confusing and has even given me some inspiration for a note-based puzzle I'm working on crafting. Good entry!
