This game has more issues than the first one, starting off, the camera is weird, and there's only one song in the entire game, that loops in every single stage (the first game had 3 songs). But now there's character customization, ability to replay levels and more. Not bad.
Despite it's shortcomings (bad graphics, slow movement, etc.) it's still a good game, definitely underrated. Don't expect to complete it if you're a casual player or don't have enough time, it's a VERY long game.
