Thanks for attempting to play, haha. So sorry to hear that happened. The jam officials did recently let us fix a bug that caused the menu buttons to lose focus. So depending on when you downloaded it this issue may be resolved.
Another thing, that I didn't realize we dont have any instructions for anywhere, is that the game is meant to be played with a controller, so that may be the reason you cant navigate in the menu. I'll go in and add that to the itch page to clarify it to others as well.
Try re installing it and if it doesnt work again let us know so we can look into if this issue was actually fixed or not.
