What began as an attempt to learn how to make VR games evolved into another version of my Underwater ROV exploration game ideas. But after some brainstorming, I ended up having a much more interesting idea! This prototype featured the player controlling a microscopic submersible vehicle throughout the human body. Their job would be to travel through the blood veins into various organs and places in the body, locating out-of-place objects, cleaning, and extracting them.

Unity's VR tools have improved quite a lot since the last time I tried my hand at VR game development. Some things still required a lot of problem solving, due to the specifics of the project having physics controlled interfaces within a much larger physics object in scene.
