Since I have a laptop, I can't really upgrade my hardware and OpenGL is already the newest avalible version. I'm using wine-devel (2.13) because the current stable version doesn't support DirectX 9.0c (at least on my hardware) and it kinda works. I can't select the screen for fullscreen mode - well I can, but the setting doesn't do anything. The game freezes when I press [Ctrl]+[Alt]. The menu is a bit glitchy which is as far as I know Unity's UI fault. You can see this here.
I won't give any feedback untill I beat it, just that I won't miss anything. (It's more like I want to be missed by the enemies ;-) ("I know my wife still misses me... But her aim is getting better! :-D"... (kill me))
I already have a video for the final boss of the previous build but I didn't upload it yet 'cause I'm not sure whether I should put some bg music although I actually think that I'll make an archive with original feeds. What do you think about that?
