Fullscreen on a 4k? No wonder it looked so small on the first vid O_o
Well the game already had its run on the usual flash sites, and don't worry about donations as it was a sponsored game after all
(also you can check out v1 on the sponsors site as well: http://bigdino.com/play/1605/LAB)
The thing is with v3 for me to be able to add the most wanted features (e.g mouselook) i would need to rewrite the game in something else first and abandon flash (as it doesn't have this feature where you can lock the mouse on the screen, and now it seems unlikely it ever will)
still it might come out one day but certainly not in the near future, thing is its a question of free time and not of money
