New game: Earthraid

[LCD]

nice little game, I was able to do level 1 easily but maybe the others will offer more challenge

It is a almost 1:1 conversion from C64. The game plays exactly equal as on C64. The difference between levels is following:
For each level the mollusks lifetime is increased by two rounds, you must wait two rounds longer for a missile and there is less water.
Its not a question of winning, but the question of score.
By the way, I noticed that BeepFX crashes in ZXBC if is called inside a SUB:

Code:

Sub BeepFX(effect as ubyte)
  poke 60001,effect
  asm
    call 60000
  end asm
end sub

Outside subs it works fine.
On C64 the game took 4 kb by the way, but coded in pure assembler, on hardware that has character based display and sprites and SID. I had to use many tricks to make the conversion working, and these use much memory. Anyway, I'm happy with this conversion.
