Gunvolt 1 has a lot of problems: clunky challenge and crafting systems, weird difficulty spike at the final boss and the lack of challenge for casual players make this game a bit of a weird one
But the scoring systems are unlike anything ever, my stupid monkey brain WANTS to go for perfect high score runs and those levels are pretty good (except Biochem Plant and Eridu, those suck) and the gameplay of tagging and zapping multiple enemies at a time is super unique and satisfying
If you went for S rank runs in the Mega Man Zero games this is definitely for you, if not the game is good tho not amazing, just disable prevasion
