How to play

The game itself is simple - fly the spaceship using WASD or arrow keys without colliding with anything. Once your health points reach 0, you die.

From the main menu you can also join another player on a remote machine in the same local network. To play together one player starts a game instance and all others connect to the IP address of the first machine.

Pressing Escape in-game opens a menu that allows you to restart, disconnect, and close the game.
