This game contains 240 bytes of code and 16 data bytes. There is
no self modifying code. In fact it is removed since the better
(i.e. shorter) solution is found for alien 'AI'. The BSR/BSF
instructions were swapped in order not to shoot always from the
same position (upper left alien). There was a bug introduced
so the bombs are now falling all over the sky. Sound 'fx' are
pretty obvious - just flush some garbage (missile y position)
to the speaker port.
Program was coded during January 2-8 1997.
There is a bug (feature) list:
1. In upper left corner missile and bomb appears (when x/y coords
2. Player can go out of the screen and shoot from there
3. Every time player shoots, 'invincible alien ship' drops bomb.
(undefined SI value)
4. Upper left alien is getting 'killed' when there is no player
missile, but due to formation shape this can not be noticed.
5. Bomb is not appearing always exactly below alien.
