If you create something people can take it or leave it, though it would be nicer if more folks took the time to thank you for your work, you were in breach of copyright but if you fix this its a learning experience and one we all had to learn at some time.
When criticizing someone's work around here, they may be right enough, but the presentation could be a little better when doing so. Particularly when the creator is giving it out for free.
This stuff may not be for everyone but I am sure someone would find a use for it and you should carry on and finish it.You might have some fun and learn some tricks with shaders etc if you take it that little bit further and you gain from it too.
You only have one life ... Abuse it well.
