Pocket Gamer: Most endless-runners don't give you a narrative - just a motivation. Temple Run is all about getting away from monkeys, and Canabalt is all about just getting away. Even the games that do dally with a proper story do so with one eye on the fact that no one's going to really care.
In Dream Chaser's Story mode, some of the talking-head cutscenes that occur before your magical sprints are longer than the levels themselves. Thankfully, they're skippable, but it highlights the fact that this is a game that often focuses on the wrong things.
John Bedford (Modojo): Don't miss out on Rayman Jungle Run while it's cheap.
AppAdvice: Dream Chaser ($0.99) by Chillingo Ltd and We R Play is an endless runner with a little more depth to it. If you’re not tired of these game yet, then Dream Chaser could be another fine gem to add to your endless running collection.
Touch Arcade: In this day and age, it takes more than a fresh coat of paint to differentiate oneself in the endless runner genre. While Chillingo's Dream Chaser [$0.99] certainly succeeds in bringing its own visual flair, its the game's story mode (in addition to the secondary endless mode) that gives it a leg-up on a lot of the competition. However, a few annoying issues with the story mode and graphics keep Dream Chaser from loftier heights.
