I thought this was great for a short little multiple mini-game experience. I think this could be made into an even bigger project. You could have Greg at the office, at the gym, working in the garage, etc. I thought the difficulty levels were on point and the mini games were fun and various for such a small area.
It may be simple and short, but I couldn't really find anything wrong with it within the realm of what you were trying to accomplish. Hopefully it's something you can expand on.
Thank you for making it!
