My scoring method:
Stars :: Description
5 :: Lacks for nothing
4 :: Lacks little
3 :: Lacks somewhat
2 :: Lacks severely
1 :: Absent
Scoring philosophy: All scores start at 5. Points are taken rather than given.
My score for Spinner Ground:
Fun - Lacks severely :: 2
Bosses - Lacks somewhat :: 3
Theme - Lacks little :: 4
Controls - Lacks severely :: 2
Audio - Absent :: 1
Visuals - Lacks somewhat :: 3
