Well, since this is in early beta, people can clearly see mistakes. I won't expect any good rating unless you fix these bugs and make the map more pleasing to the eye, (Instead of just "Copy, paste, move/resize, release"). Although this is still in very early beta, I would suggest you get more people to beta test for you and fix some common errors before you post on here. This looks like a cool idea though, so keep at it and hopefully it will turn out nice.
Sorry but this map looks like it took 2 hours tops. The idea is pretty cool but if you want to actually make a map like this the map should be longer so that you can actually appreciate the reason why you're taking out chunks/ideas from other maps.
