It's more of a level pack for Jumping Flash than an entirely new game, I honestly but the things it does change are all an improvement. More expansive areas with great atmosphere, more challenging stages and bosses that felt less easy to cheat, and a (very slightly) more complex plot that adds to the charm of everything. I might like the original game's soundtrack more but this one has some individual bangers. Might be kind of the same game but it's easy to get into after the first one and some of the new scoring elements add replayability. Definitely recommend if you liked the first game
