Orbient isn't about engaging visuals or complicated controls, nor is it about complexity. What Orbient shines at is creating an experience that is fun to play as an escape from hardcore video games, yet at the same time engaging enough to play for hours on-end. The pick-up-and-play nature of the game may turn some people off, but once you get under the game's skin, you can see that Orbient can be played for hours.
Yeah, the lack of online and leaderboards hurts the game, but for 600 Wii Points (the equivalent to $6.00 US), what do you expect? Orbient is all about accessibility and bridging the gap between casual and hardcore gamers.
