Playability:
Really great game overall and something that could be used to great effect in educational environments. You should honestly pursue fully creating this game. Nice work.
Theme:
Doesn't fit the theme strongly but that's just fine. You've made something that is incredibly compelling despite that.
Cleverness:
Really clever use of puzzle mechanics here. I really enjoyed the multiple modifiers possible with the moons. Can't wait to see how you expand this.
Artistic Style:
Silly facial expressions and easy to understand art direction. Overall solid work and good experience.
