I'm going for like a 50-50 mix of Pizza Tower and Undertale vibes so there's story stuff happening in-between going fast, but fluid movement and going fast always was a priority.
Some tips:
You can disable dialogue in the Speedrunning options if you really want NO story
Always hold the run button (it increases your jump height even when standing still)
You can stack the recoil from the basic spell to go over the regular speed limit both vertically and horizontally
On levels with more than one Crystal Burger you can collect more than one in the same run to Double Flip, this is basically the "Lap 2" mechanic
