Rainbow Cotton is a 3D shmup with a forward perspective akin to Panzer Dragoon or Star Fox, but it is unfortunately very clumsy in design. Cotton's model takes up far too much of the screen, obscuring the enemies and crosshair, which loves to snap to the centre. On top of spongy enemies and a finicky EXP system to power up your beam, it's shockingly difficult to kill anyone in your path, let alone know you're even hitting them. The pathing is weird, too; you can just bounce and clip around the track haphazardly because the camera tracking is nigh impossible to predict. The experience is honestly so grating it's insane.
The saving grace is that this is imo the best looking Cotton game - charming anime FMV cutscenes, and low poly pastel coloured models and environments that are so kawaii in that Spyro PS1 way.

A curiosity is all this ever amounts to, if ever you want to experience a game that is bad enough to bury a franchise in the ground for twenty-one years - you can with the newly-released English fan translation!
