Alright, mixed bag here.
Good: Graphics are cute, does a good job of showing what is needed visually without explaining.
Bad: Too many dead ends and paths that lead to nowhere, leaving exploration feeling kind of pointless.
It feels more like a prototype then a full game, albeit a good prototype, and considering the time resources its understandable why. It seems like most of the time was spent on the angels themselves, which admittedly do look quite good, the animations are all very charming.
