Version 1.1.0 is just released. It's custom mouse cursor now, so it should work. If not, you can start the game by simply pressing "Enter" on the keyboard. Also if you want windowed mode, there is now an option for that in config file.
It works great now. I might suggest making the paw "pointer" a slightly different color. It's a little difficult to see against the darker title screen. Excellent work, overall.
