Fun!
I really liked this game a lot, it reminded me of Pipe Dream.
The only problem I had with it was that the cow would constantly moo... and it was really annoying because I was really diggin' the african music in the background, it went really well with the game, but that damn cow...
Anyway, great work. Much fun. Put more then 10 levels in it if you ever make some sort of sequal or something, though.
