I ended up liking this game, even if it wasn't all that great. The gameplay really did appeal to me. It's mostly because it's easy for me to understand. I still enjoy figuring everything out. The music is quite good too. For a game about dung, it's actually not that crude.
A lot of times, you just have to experiment with it. It's a great game to play as you go along. I don't think there's any difference between the stumps and mushrooms. It's pretty nice to have an easy going game like this. I quite enjoyed it.
