Should probably share controls for this...
In platformer stage:
Move: WASD
Dash: Left mouse Click
In Free Flight Stage:
Move on Planetoid: A for left, D for right.
Launch: Space
Create Dust Storm (Use these to land on/jump off of): Right click
Note: You can't get out of Free Flight mode. There are no gems to collect. The monster is a giant sphere and can't eat you. But you can still jump around, so there's that!
