Slow Start (Essentially spamming j/x/shift+a/left at the start to drop faster)

Moon Jump (Spamming space/w/up to jump straight up)

Double Soul Jump (Using the soul two times in air, this can be done by using a short soul and then press again the soul key)

Soul Teleport (While entering a level there is a 33 frames span where you can glitch your soul and store it in a precise spot, so if you press the soul key again you will teleport to the old soul)

If you discover a new mechanic or glitch that can be used please DM the moderators or make a thread. Hope this helps
