When I start the game (not a bug), I think the loading buff (white screens) are a bit.. long F1
If possible, I think the time should be decreased a bit.
Also.... [hits head] I just forgot! F5
Oh THAT'S RIGHT!
I'm not sure if you can fix this, but if you minimize FS a lot like me, it just pauses and does nothing. This can be quite annoying for people who IM a lot like me F3 (If I'm waiting for the enemy to finish their attack, for instance).
