Could you let me know what your screen resolution is?
Currently the standard size is 1920x1080. If I knew yours, I could simulate it, and then I can put in a system that resizes based on that possibility.
I appreciate you letting me know :)
I've also added today an update which auto-determines whether you can fit the screen with all three columns and if not, it switches automatically to a compact mode. The options menu also has a secondary compact mode which compacts the right column instead of the left.
This should help people with lower resolutions play more easily.
