I work for a company just like this. We use Unity (and lots of other game tech) to make games for health, mostly for physical therapy and rehab. There are interesting problems to solve in this space and we're putting good energy into the world with our work. And, we're hiring! If you (or anyone else reading this) is looking for a great job and know a good amount of Unity/C#, drop us a line at [email protected]. Remote work is fine, too.
