This is a little yet unfinished RPG I made with c#. I'm asking you guys if you think this code is correct and optimal. It runs well but I'm wondering if there are things I could improve to make it more clear or optimal, basically I'm asking for some feedback and suggestions.

The program is obviously not finished but I'm asking now before I move on so I know if I got some serious design or logic issues there. I'm beginning in programming so keep that in mind when answering :)
