Thank you for your good comments!
I'm working on it, it has an editor, the interface is better to handle and it has more music now. But I can't upload it, because I'm away from home, so I can't upload it at my server and I don't want it upload on ifile, so I'm going to upload it next sunday

But I have no idea, how to fix that with the ingame upload and download from the levels on the server. Has anyone a tip for me?
