First thing: here's the game - https://lukeoc.itch.io/kuxtal

This game's speedrun relies on changing the Unity settings to make the game run faster. The rate of the character's super jump recharge was mistakenly tied to the framerate. This means if you run the game at lower and lower graphics settings, you can essentially spam jump boosts. In practice, this allows for very fast movement through the map, so much so that the player can go through walls or easily out of bounds.

If you'd like to start speedrunning this game, just go for it! It's not very competitive, and it's easy to play.
