SPICE INVADERS
You might think that it doesn't really exist, judging by the guys other videos, but once upon a time if you followed the link in the comment, you indeed found a playable version of the game, and it played just like the video, though it didn't have the same intro cutscenes. It also gives you three lives instead of just one.
Well, I just happened to archive that game.

http://eunich.cochems.com/~zaphod/SPICE%20INVADERS.lzh
arrows to move, z=spread shot, x=focused shot (slow move and shows hitbox),c=bomb (you get 3, +1 each time you die)
Game records the top 100 replays for later. press C to bring up the replay list.
Have fun people.
I apologize for the archive format but i figured it's best if the original archive was untouched.
