itch.io

I don't know if this is just me. When I open the game, it shows the engine logo, opens the title screen and starts playing the music. I hop in, my FPS drops to 30 and it turns to like 140p and whenever i try to click some windows sounds play and the game crashes and i try to close the folders window and it stops responding and my screen goes black. All of my desktop applications get moved around. My computer is good and able to run the game fine. I don't know what the hell happened. The first time I installed the game, it worked ok. I tried to edit the sign in front of the shop and the game crashed. Now every time I re-install the game, the thing I just talked about happens. Any possible solutions help.
