Providing a a way to put the program into true full screen mode where TitleBar and manure bar are hidden would be great. Maximized window is ok, fullscreen mode is better.
Just a warning though, since you are using <ESC> for ending the ride you will have some confusion when you implement fullscreen mode. <ESC> is generally accepted as “exit fullscreen mode”. Might want to consider re-purposing <ESC> during this beta phase and maybe moving to a keyboard shortcut of <e> for end or <p> for pause.
