A bit monotonous for how long it is, and it definitely needs a mute button--I've heard enough of those reggae loops to last me a lifetime. I like the graphics, though, and the deaths are a nice touch.
The first one was good; this one is great. It does need a volume control available at all times and it lags my computer, but I love the expanded worlds and the art.
The game engine needs a lot of work; in a game where it's important to make certain times, controlling your character shouldn't be the biggest problem. Especially look at jumps and friction.
