It's a tech demo of a game where you're a wizard interacting with the world via fluid dynamics! Drag the air to blow it around, add heat, burn grass and bushes (and yourself, if you're not careful!)
If you download it, please tell me if and how well it ran on your machine. The fluid dynamics are a bit resource-intensive! You can get performance info with 't' and 'g.'.
You have a character now.
WASD to move him around
LEFT CLICK to add heat into the world
RIGHT CLICK + drag to blow air around
Heat hurts you as well. (No health bar yet, I'll try to add that by the end of the weekend...)
The goblins walk towards and away from you, but they're not very clever (they get stuck on the walls) and they can't hurt you yet. You can blow them (and yourself) around with wind, though! Or burn them to death (you monster...)
'r' regenerates the map
'z' generates a flat plain
'f' reverses the flow of time for fluids (sort of).
in general, most of the arrow keys do something debug-y.
