I discovered this while just messing around trying to find another way to pass through the train. As it turns out, there is one. By holding down the down arrow key and opening a new tab without releasing it, and then waiting a couple of seconds before switching back to the game, your character will walk through the train.

Unlike the previous method, which was very incosistent and hard to pull off, this one is super consistent and will work pretty much 100% of the time as long as you're doing it correctly.

Sadly, I don't know how this would work for a downloadable version of the game. I haven't tested it myself, but maybe there's some alternate strategy? I don't know.

Video:

The boat glitch is a glitch that allows you to skip the second or third stage of the boat race. It's only useful in minigame%, but it is VERY useful in minigame%.

You can perform the boat glitch by finishing the third lap of either the first or second stage just before another boat finishes the second lap, as shown in the video. This will skip the next stage completely.

(Note: the timing is pretty precise, but you should be able to get fairly consistent at it without too much trouble.)
