Adventures of Shuggy
is an indie platformer that deserves to be more widely known. It has a lot of content. At release, there were already a single-player campaign and a few dozens of co-op levels, but a free DLC was added that adds new single-player levels. All in all, there are almost 200 levels to play through (156 solo and 36 co-op).
Overall, the difficulty is well managed; some levels will prove to be challenging but none are impossible to beat. I was rarely frustrated by my failures as they were never due to a broken mechanic but rather to errors on my part. Level completion is timed, so you can compare with other players through online leaderboards. It took me about ten hours to complete the single-player levels.
As for the art, the visuals are cartoony and well-done. Cutscenes are present in the form of comic strips which complement well the game's graphics. The music is enjoyable, though it becomes repetitive by the time you've completed the game.TL;DR
: Buy this game, given the price you don't have much to lose.
