A personal favorite back in '06, it brought a bit of lore behind the original Pico's School and the character himself! Heck, it was even brought to canon after Pico vs. Convict. Quite amazing though even for such a aged series.
This is quite the challenging game, much like the original Pico. Gangrene would be the most hardest due to the approaching missiles, Gangrene flying across the map, and a set time limit. You really need to be on your toes for that one!
Solid work, a classic.
