I haven't had time to test this properly yet but first impressions look very good (using CrossOver 12.5, game installed into a fresh bottle with only "DirectX Runtime - Modern" installed). I've only gone as far as loading the first level & running about a bit but everything has worked fine as far as I can tell - the game loads, menus work, first level loads, cutscenes and gameplay all seem to work well; the framerate appears good & there's no stuttering or glitches that I can see.


System specs:

Linux Mint 15 KDE 64-bit on i7-2600k @ 4.5GHz, 8GB RAM, Nvidia GTX 570 (driver version 313.30)

Update: I've now played through the entire game. I did not encounter any crashes, did notice a few very minor graphical oddities but these could easily just be quirks of the engine used; I probably wouldn't have even noticed them if I wasn't looking out for them as I played. Encountered noticeably lower framerates in some areas but I hear this happens on Windows as well... wasn't really bad enough to affect gameplay anyway.

Overall this seems to perform extremely well :)

It seems the developer might have problems making interesting levels, but at least know how to program ;)
