I really like the use of the limitation with constant movement keeping your body temp high, but unfortunately holding down both the Move keys and Dash key at the same time didn't always respond.
The Dash key right next to the Move keys made it awkward and unnatural to control too. I would have mapped the Move keys to the Arrow keys too and the Dash key to Shift as well. That way movement could be on one hand and jump and dash on the other.
