Hey there! Sorry it hasn't been running smoothly for you.
So, Woodsy was made for a game jam, meaning we only had a weekend to make it as a kind of fun challenge for our skills, and to that effect we tend to forgo things that would be important for a full game release like an options menu (or really any menu at all) in favor of finishing the core of the game. So no, right now there's nothing you can do to change the graphical quality and make it run smoother, but there may be a way I can prepare a more optimized build for you to be able to enjoy it. I can't promise it any time soon, but I'll see what I can do. :)
