Thank you very much for your comment!
Yes, the doors don't work well, I have to see how solve it. And the Quit button doesn't work (I don't know why, I will try to make it work next week). The combat part was an experiment from my part. I had never done a melee, always going for a shooting one, so I really didn't know what I was doing. Now, I see what I need to add to it. Thank you!
