You had five or something and that's way too much...

Well, here's also some criticism, because you've 50 maps, which are mostly bad and it can't go on like this (Sorry, but this had to be said :/):

1. Put more effort and time into your maps. Try to make them perfect.
2.Improve your tilesets. This may not look horrible, but it could look way better.
3. Don't place to many enemies in a row. It makes the map laggier and is senseless.
4. Improve your gold placement. Not too much, but also not just one piece of it. I also don't know how I should reach the piece of gold in this map. Another thing: Don't hide enemies; in other maps you did that very often.

These are the most important points, I think... Please take them serious.
It would be also useful to read this [forum.therealn.com]. You don't have to read everything, but taking a quick look doesn't hurt. ;]

... But I have to say, too, that sometimes you're concepts are very nice, you just have to pack them into a better package, if you know what I mean...^^
