The last time i did LD, it was a 2D game. So this time i did a 3D "game" one again using JMonKeyEngine. I had a lot of fun doing this. But unfortunately "This" is not really a game there a no objectives, maybe it's up to you to find the way you can have fun with this entry.
At least you can still play around with the elements, and try the physics boundaries of your graphic card, like a kind of benchmark ;) .

-- Controls --
T - toggle azerty/qwerty keyboard
ZQSD / WASD - Move
Mouse - summon the elements and look around

-- Bonus --
P - toggle physics debug
M - toggle Graphics stats

For the sound just search "Storm, Earth and Fire" ;)
