It's visually cute, the style is simple but interesting, and the gameplay is functional, but I feel like as a mechanic the shapeshifting aspect is fairly underplayed and the game is more about exploring a narrow environment. The camera is rather unfriendly, a lot of the time it feels like trial and error to figure out which part of the level actually exists to explore and which part exists to fall off and restart. More of the map could be shown to the player.
That might be a limitation of mobile design, since if the player were too small they'd be hard to manipulate, but I don't think this is the happiest middleground there could be.
