The good:
- Really unique and fun dungeons (especially the last few)
- Cool story
- The items are fun and can be used in each area instead of just being one and done
- Returning to previous areas is interesting (the first time)

The eh:
- The world feels less "lived in" with no overworld or towns
- Each area is designed like a dungeon, which is fun but can be overwhelming
- The sky is boring
- Backtracking gets old by the end
