It is bundled with a DOS-emulator to work on a modern PC.

Left/Right arrow key to choose difficulty. Press Enter to select.
The game was made for the Medium difficulty. Recommended!

It's really simple. Use the arrow keys to change direction & jump.
Each press on the arrow key jumps over 1 spot in that direction.
No press continues in the same direction until crash with border or obstacle.

If you last 30 seconds, you are good.
If you last a minute, you're a God!
