You might have played this in the last demo day. There's more stuff!
In this prototype, you can move the camera around, add heat and wind to the world to watch how things swirl and butt up against walls, kill those funny little goblins, and burn things made of grass (which in turn adds heat back into the world!)
CONTROLS:
WASD to move around
Left click to add heat
Right click and drag to blow the air in that direction (Try holding both!)
Click middle mouse to rotate camera
ESC to quit
R to re-generate world (takes a second)
L to toggle fluid sim debug window
...And a lot more...!
I've briefly tested on windows, but please tell me how it runs if you play it- and crucially, how it feels to blow air around!
