Took me a couple of tries to get into it, but once I understood what I was doing (it probably took me way too long to understand that you could manipulate how your tower looked and that it wasn't completely random :D) it ended up being a pretty fun game! By itself, I think the tower building mechanic wouldn't have been too interesting, but combined with the money management, little jokes and great art style I think everything comes together nicely.
Edit: I saw your comment about not getting highscores working from webgl. By any chance were you using a highscore website thingy like dreamlo? I'm pretty sure you needed SSL to make that stuff work online.
