Thanks but it has some little bugs (they don't affect the usability, but I want to improve it technically).

However, since I already rewrite it, I can put changes into it. Thus the oppinion of those who critisised it is quite important to me.
Maybe they can describe it more specific.

And yes I'm working alone.
Blitzblaster was so kind and made a Dragonrise-BGM song for me which I really like.
