Marble Madness

The worst port of Marble Madness I've ever played. Compared to other versions, in the GBC port you literally need A LOT of luck to properly complete the game, and that includes exploiting a glitch at level 5 to skip the bird obstacle (which saves time but 99% of the times that's still not enough). Conclusion: you should definitely pass on this version, and play the NES or Genesis ports instead.
