Jumping ACTUALLY makes you go faster on minecarts. Might only apply when you are going uphill.

When controlling a minecart, keyboard input fully overrides analog stick input.

limbus found a weird minecart thing on the minecart elevator in the middle path of Chests (it’s documented there)

I vaguely recall Aroymart finding a variety of weird minecart stuff. for example:

hey I think if you spam zoomies you can get off of mine rails like a 10th of a second earlier

In this video, Dr Revert manages to do a glitch that makes the minecart doors open even when Croc walks up to them without being on a minecart. This is in the demo WAD for Chests, which is why the side paths are missing. Perhaps this can be done in standard levels as well?? Excerpt from the video description:

At the end of first gameplay I wanted to execute a glitch I managed to activate later, to freely open gates without using the cart. However the camera got stuck for some reason.

Holding left + right simultaneously

For some reason when leaning left using the keyboard, if you hold right simultaneously you will tilt a little to the right. This can be used for collecting a Crystal near the start of Caveman Jigsaw without dying. Unfortunately, you can not do it by holding two analog sticks in opposite directions or by combining analog and kb input.
