So I recently upgraded to Windows 10 but I can't start the game. When I try to start it nothing happens then I look in the task manager to see that java is running in the background but the game is still not starting. I didn't try to reinstall the game and I doubt that'd work anyway. What should I do?
I've found this short article on the wiki: https://wiki.spiralknights.com/Technical_issues_FAQ#Windows_10_Help
Also, are you using Steam or standard client?
I'm able to run SK on Windows 10, but there are some issues. It used to crash after shorter lags before I updated Java and some glowing effects flicker for some reason. I have Steam version, but I can test the other one if you wish.
I'd like to help if I can, but I don't know if I'll be able to.
