Great time Waster
Not sure what everyone is talking about, only reason I gave it a 9/10 was because it was too easy.
Start off upgrading your sling shot and abuse the Ice food. Never upgrade cat storage, chance, or barricade until the sling shot is maxed out and it is easy sailing. Don't think I ever got below a quarter.
It got fairly repetitive and I found the invisible food to not really be worth using. Though I enjoyed the game tremendously for the half hour or so that I played it.
