This is the second in a series of seminal platformers for the PlayStation, with very similar gameplay to its predecessor.
A normal run of this game takes a rather long time to complete. However, by using a bug that corrupts the memory when jumping on top of an unbreakable box, the author gathers the crystals necessary to advance to the next set of stages unbelievably quickly, leaving only the bosses to make quick work of.
Note for viewers: The PSX emulator PCSX-RR is unable to play most sounds from this title. Thanks to the efforts in resyncing every second encode link leads to an audio restored version.
