While I DO like to collect the skins, I feel like the levels in my honest opinion are too long and the checkpoints in-between are torture. This game induces lots of rage and frustration when you miss 1 box that was hidden off camera. Overall though, it is different and the graphics are the best I've seen in a while. I enjoy the different characters you can play as, though I really hate missing jumps as Tawna because I wasn't perfectly aligned with the grapple icon. This game IS frustrating, but it keeps you going back for more. It's a love/hate situation for sure!
Personally I wont attempt the time trials for sanity sake past the first 2 maps.
