 # Usage
 
-You can pass `--help` as an command line argument to print help message. You can force incomplete TUI mode that exists for a demonstration of portability and independence of SDL. This TUI mode is incomplete only because it's missing few UI elements and not because it is not feasible. You can also force other sizes of the game area.
