Klang 2 is a very solid entry in what has become a niche genre in the past couple of console generations. Tinimations has done a wonderful job of building a more tightly tuned follow-up complete with a hard-hitting soundtrack.
Once you get used to the feel of the controls though, Aeon Drive is a fast-paced platformer that is sure to offer you a decent challenge. Especially if you take the time to grab all of the collectibles.
If you are looking for a short puzzle-game, with a nice, classic visual-style, and some satisfying puzzles to beat, then Gardener’s Path is well worth the buy.
