Probably one of the hardest aspects of game development is coming up with a suitable sequel to a popular and critically acclaimed title. There is a fine line between keeping the elements players enjoy without seeming stale or making the game look like a lazy cash grab, and that of changing the game too much that it alienates its intended audience.

Somehow, the pairing of the Toronto-based studio Snowman and UK artist Harry Nesbitt, operating under the banner of Team Alto, has managed to walk the line successfully with the release of "Alto's Odyssey."
