Thanks for the feedback!
Yeah, fine-tuning the camera wasn't something I had gotten around to yet. By the time I got the core of the game working (for the most part), I realized I still had the UI to do, and UI was not something I'd had the chance to work with yet in Unity. It was a pleasant surprise to see it was mostly HMTL/CSS based, but still a little bit of a learning curve. I actually had to skip ahead in the ZTM game dev course to get it done, so it's sort of a partially hobbled-together statemachine as I picked and pulled what I needed to get it done.
And since I hadn't learned UI yet (or making cut scenes), story wasn't a huge focus for me in development. I do see this potentially becoming a small part of a larger game, maybe, but there is only so much new stuff one can learn in such a short amount of time. I did try playing around with the particles system a bit too to try to make the ghosts stand out more, but I couldn't get an effect I was happy with, so abandoned the idea in favour of what I could do in the time allotted me :)
