Are you using 0.3.1? It has way better performance. if you already are, change the game to a window in options and shrink it a bit. As for the auto left thing, I don't know. Which version are you using? Maybe that has something to do with it.
I am using 0.3.1. I know how to deal with the fps, i will just go back to my smaller monitor as the pc can't handle the bigger one, but i guess Steven will have to deal with the auto-left thing, it's also bugged both on 0.3 and 0.3.1.
Hmmm, multiple times? I'm assuming that you've tried opening it more than once and keeps happening, but need to know. Also which computer version are you using, windows?
I don't know why that's happening, it's weird that not everyone is having it, yet it isn't isolated. I must be in the way certain computers are interacting with the code or something.
