I watched and listened with great interest and I learned an awful lot from your video. The overall idea you have for a game is great but as it was your protoype I don't think you will be coming back to this one but rather moving forward with your newfound knowledge to see what else you can produce. I could be wrong.
However, you did spend a lot of time learning unity and the mechanics and I totally understand that in the early stages of learning it can be a total head bomb, so I'd like to say well done and to also wish you all the best.
