Enjoyment: Really nice, I enjoyed exploring planets and having to choose what planets to go to so I don't run out of sun dust. One thing that annoyed me was the intro playing after my first time seeing it and it didn't seem like it was skippable. Another thing that was weird was the landing but I assume thats a skill issue though it could be better.
Concept: Good!
Presentation: All the art is amazing and polished but I especially like the art derpyzza did.
Use of the Limitation: It's amazing. You could have made it much worse by making you not able to reach the sun but that would've made the gameplay worse so I'm glad you chose this way.
