I've been searching around a bit, but I can't find a cool shooter I used to play many years ago.

I played it on a russian 8-bit famiclone and the spaceship was flying around in an organism or something. I don't think there was just one level inside an organism, but that it was all set in one.

At some place you have to shoot yourself through walls of cells that regrow and there were bosses like a brain with tentacles.

Anyone know what the hell it was? It's been bugging me for a while
