This might be the ugliest game I've ever played and it's not cause of the "Anime Fan-Service" Aesthetic.
Rabi Ribi suffers from the worst case of style inconsistency imaginable.
The quality, the art-style and even the pixel size feels completely randomized.
And i'd generally say this is worse than when a game consistently amateurish in it's art, cause at-least it's consistent.
For a Metroidvania it kinda loses a lot of the fun in exploring cause of it being such an eyesore.

But I gotta say the combat is pretty fun even if the animations are really awkward.
And the boss-fights are quite fun even if they can be quite dragged out.
