Off the bat the art is delightful, good sprites and some lovely animations, that said the mechacis are original but full of "moon logic" you have to play the game knowing what the game wants you to do so it takes many deaths to get anywhere, i stopped playing after i was doing the forest and my screen froze at a screen unable to move or perform any input.
Theme wise, it fits, there are little times where the "only one" line gets dropped but not a major mechanic.
Originality, definitely but in a way that hurts the game a bit, but better to aim for the skies. The game showcasts the dev passion and creativity, hope he iron outs the design of the game and i will be playing other games from it in the future.
