HunchBluntley: This game is one of the ones GOG apparently wasn't able to reliably get working on Windows 10, seeing as how they don't officially support its use on the new OS.
Bronther: Is there anything I can do? I don't really want compensation I want the game to work. Is the dev working on a patch? Should I just wait?
Don't know. I haven't heard any details, and I haven't upgraded to 10 myself, so I can't help with ideas of what tricks might make it run better. Since you don't want a refund, waiting is probably the best bet. In the case of this game, I doubt the developer will just let the game stay in an unplayable state; after all, it's not very old yet, and very highly regarded, and -- if fixed for the new Windows -- could yet make him a fair bit more money. On the other hand, from what I've heard, it was pretty much a one-man development team, so -- depending on how busy he is with other stuff right now, it might be a bit of a wait for him do get such a fix done.
I would also advise browsing through [url=http://www.an-ovel.com/cgi-bin/magog.cgi?ver=604&scp=gdspr&dsp=ipgsorlcmxX&ord=&flt=onn~w10~&opt=&myf=WedAug122131272015_l6oP2gBd_4IAL]this MaGog search results list[/url] to see what other GOG games you might own are not supported on Win 10 right now. I used this info to apply a custom "Not supported on Windows 10" tag to all games in my GOG game library that are on the list. Hopefully, the list will shrink as GOG (in the case of some of the older games) and the game developers (in the case of some of the newer ones) are able to find ways to make these titles compatible with 10.
