Hi Tenchfroast, glad you like it the game. Of course, there is a lot to improve but I'm working on it. Thank you for your feedback. About the stamina it's just restored when you stop running, I think it's restored pretty fast, but not over your overall tiredness, so to have full stamina bar you must sleep or rest on benches. When you have full tiredness bar you will have full stamina bar. If you have any other question, just let me know. Cheers.
