Yes, this is yet another version of Space Invaders, but with this one I'm going for a direct port of the original arcade game. It's mostly complete, with functional gameplay and a working high score save system, but it needs some gameplay tweaks and a few graphical elements, and the sound effects are very much unfinished (I'm working on a version of the 4-tone march using subtones, but haven't ironed out the glitches yet). Anyway, in addition to going for authenticity, I also tried to code this very efficiently, and the whole game (including all graphics and sound), takes under 3KB and only about 1100 tokens.

Any constructive criticism and general feedback is welcome, thanks.
