Can't get into Madagascar, ever. Dumb game design. There's literally no way around it, it's just restarting and doing the exact same thing until you get lucky.
This is one of the worst games I have ever played. Awful design, nonsensical progression, no explanations. There is no way this should ever have gotten on to the "Best of 2007" list.
This game is unplayable. Lags to hell. Can't even get the basic achievement because the game lacks the control to get the Superman upgrade by anything other than pure chance, and I'm not going to play it long enough for that to happen.
Very bad game. Interesting idea to start with, badly executed; little to no explanation, bad balancing, becomes very difficult and/or tedious very quickly.
