A great game, definitely reminded me of hover bover, and I was thinking of the tune, "in an English country garden" all the while playing it :) I don't know if I broke it or there were no more levels but after exiting the 3rd he just mowed off into the sunset :) It might be because I wanted to find out what happened if I mowed all the flowers as well, I was hoping for an irate home owner or park keeper.
Controls tricky to start but easy enough to pick up, and even better when I realised I had to get to the exit sign not just the path at the end.
