Did you download newest version?
it is ob3d_0.9.9.2?
that's my version
Yes thats the correct version. Did you unpack? And dont put it in One Drive folders..and make sure virus protection doesnt mess with it. Anyway its coming on steam as a demo very soon, im sure it will work there
If you can open the game but cant fight, it could be a graphics card driver problem..maybe updating your drivers might help
