A great idea with great execution. Many devs have trouble with puzzle platformers, often making levels too complex too fast. But this game had ease and flow to every level. The mechanics were introduced gradually and nothing felt overwhelming. The physics are well tested and integrate seamlessly into the puzzle design. I felt like a genius every time I found a solution, as if it were my idea! That "aha moment" is hard to create in a player's mind, but this game does it constantly. The game felt...very zen.
The graphics are gorgeous and I love the kanji characters being actual characters with faces.
I don't have a single nitpick. I'm looking forward to the full release!
