Playability:
Intuitive gameplay with a novel game mechanic is very hard to achieve. You've made something really awesome here.
Theme:
Directly fits the theme in that you viewing the environments keeps them from degrading. Incredibly interesting direction on this.
Cleverness:
Never seen a game using this kind of mechanic before. Nice work.
Artistic Style:
Simple and consistent programmer art. Honestly it doesn't need to be more than this.
