Space Invaders is a fixed shooter from 1978 in which the player moves a laser cannon horizontally across the bottom of the screen and fires at aliens overhead.
A few adjustments in v1.1.1
On every new level all invaders move one row down. Maximum row to start is just above the shields.
All invaders should always start moving to the right on every level.
Sometimes a mystery UFO would be created when you just finished a level. The mystery UFO would continue on the next level. Fixed this by stopping the timer.
For those interested on how I made this game, the *.c3p is available for download. If you have any comments, suggestions or explanation, just let me know.
