The classic Asteroids.
All wrapped up into a single drag 'n drop behaviour!
Drop the behaviour onto a sprite containing a bitmap castmember. Choose the controls, and the foreground and background colours, and that's it!
The game scales automatically to the sprite size, although small sizes makes for an unplayable game.
Use the keys as shown on the title screen, and play to the death!
Extra lives are awarded every 3 levels, up to a maximum of 9.
If running a DCR, you may have to click on the game first for it to react to keyboard control.
