Glitch Passwords
The password system seems to have been crudely made with a lack of error-trapping, allowing for many glitch passwords to exist. Take note that the highest level you can legitimately reach is 60, and there are four "bonus levels" only accessible by password (S1-S4) or death by eating the carrot with a forbidden mark, rounding out the level count to a perfect 64. Beating S1 (Stage 64) will not reset the stage count or display an ending; instead the game will proceed to the glitch Stage 65. In the Japanese version, the game does indeed partially error-trap during the loading process, taking you to a legitimate level (but in all other respects is still the out-of-range level) instead. Beating this level will send you to the next "fake" level, but if you die once you'll be taken to another (fake) legitimate level (always 2-3 levels ahead of the level data generated in the Japanese version) instead. This is also glitched, as the level data of the level you "warp" to is usually wrong and doesn't match the level number, and you'll keep warping ahead every time you die. After this it doesn't matter if you die or complete the level, you'll still continue to visit fake/mislabeled levels. This death feature also applies to Crazy Castle, but since the levels in that version are glitched out, dying either happens or it doesn't, since you're at the whim of whatever garbage that generates. For some reason the game won't give out proper passwords for some early glitch levels, instead defaulting to the password you used to access the level. It's unknown if this was intentional or not.
A sample list of glitch passwords follows; this may or may not be moved to a Notes page in the future.
