Hi !

I was focusing World 1 levels until I stumbled on those weird Spike skips (where you jump on the right momentum to get a boost that makes you skip a spike for -1 health) I wanted to train that and were wondering if there was any practicing map to this method or anything ? :D

Anytime I've ever needed to practice a trick, I would just work on it in whatever level the trick is in — sometimes in story mode to skip the previous rooms. Otherwise, it shouldn't be difficult to recreate an obstacle yourself in the level editor, especially if it's static. If you mean the wall spikes, you can just make a wall, place some spikes on it, then put a checkpoint below for quick healing.

If you want a practice map for other tech, Bghty has a discord link in a video description, but it's more of an obstacle course than something for practice drills.
