New Year's bug fixes

After the last update with Achievements, many people started complaining that the game stopped launching. To be honest, we still don't know what it's related to, but we tried to fix some things... hopefully the problem has gone away. Those who had problems with the game launching, please check if it started working now?

And a little bit of goodies. First of all, the game now starts by default on full screen (previously you had to press F4). Along with that, there is now an “Exit” button in the menu.

Secondly, the styme overlay now works, and achieves are displayed on top of the game in fullscreen. As well as windows with friends list (if you have friends) and other stim stuff.

Anyway, sorry to those who had it broken last time, double sorry if it hasn't been fixed yet (we're honestly trying), and Happy New Year!
