Bodies freak me out. It's just a thing. I've been afraid of bodies, organs, etc. ever since I was a child and had to participate in a mandatory health course at school which took place in a cramped, dark van covered in posters of diseased organs, anthropomorphised body parts and this atrocity:
Guess what, that digestive tract lit up.
Unfortunately, there are few games that really exploit my fear and I'm no dev myself, so I'm calling upon you guys to make my life really horrible.
The prompt: an educational trip inside an organ or system where the enemy is not meant to be there. Perhaps you can take inspiration from a certain Rick and Morty episode, or perhaps even a toyline I enjoyed/hated when I was very very young: http://www.strangekidsclub.com/2015/04/06/toychest-time-machine-body-wars-by-toymax/
It can be 3D, 2D, a platformer, anything. While I say enemy, combat with the player isn't necessary -- you can get away with the assault being on the environment itself via some depiction or representation of a disease or parasite. Every entry will have my fullest attention and will receive a dedicated review...and my HATRED.
I hope you guys consider entering!
