Heat Prototype

WASD to move
Mouse to look
Space to jump and double jump (double jump uses heat)
Shift to boost speed (uses heat)
Ctrl to wait (lowers heat decay)
R to restart if needed.
Stay it orange warm areas to recover heat, yellow pellets restore a small amount of heat and reappear once heat has been fully restarted in a warm area. Avoid blue enemies who consume heat.
Red and green parts of the environment change at different heat levels. Figure out when and use them.
