Amnios is a unique game where you fly across grotesque living planets, shooting planetary organs and horrible creatures, culminating in fights against large boss creatures. The Giger-esque graphics is by far the most impressive feature of the game, created by the talented Pete Lyon. The game is unfortunately rendered almost unplayable by its extremely low frame rate. Music and sound by Tim and Lee Wright does not quite live up to their usual standards.
Oh, yes and one very important thing: you select items with Enter and use them with Space. Note that you have to use your weapon powerups for them to take effect!

I started from level 1, leveled up my weapon fully (I don't think the weapon gets more powerful after the final change in graphics), saved a few humans, and stuck close to the Fatherships. I ended up defeating the last boss with 9 lives left. There may have been even more, as the lives display seems to clamp to 9.
