Boulder Hill

Boulder Hill was a map added in the update on 12/11/2020. It consists of two sets of three caterpillars that can knock you off on some ice that resets you to the beginning of that specific set. The next part has a narrow pathway with cannons firing balls at you, and if you get knocked off, you get to a bunch of trampolines that lead you to the next part, a narrow path with balls coming towards you.

Strategies
At the beginning of Boulder Hill, you can jump on top of the caterpillars. The optimal way to do this is to approach it from the side and double-jump. When you get to the end of the caterpillars, you can jump on a small orange platform beneath the caterpillars to skip dodging them. At the end when you get to the narrow path, you can jump on top of the blue platform with very precise timing, and from there can jump from blue platform to blue platform to the end without having to dodge the balls.

Trivia
It is one of the two maps that can only appear on round one.
