Summary: A very original concept for a relaxing game. A good replay value even if you've finished all levels. If you get it at a discounted price, that's a good deal. The kind of game you play between two games, to make another part of your brain work.
Summary: Osmos would like to make you believe that it is a relaxing ambient game, but that is mostly not true at all. The description even makes the laughable usage of the word "elegant" to describe its game play style. It couldn't be farther from the truth. The controls are clunky, obtuse, and unprecise.
Summary: Osmos is an intense yet subdued little game. Fun on every level. It could have been done with 8 bit graphics, but it wasn't. It's very polished and smooth (assuming you're not running an 8088).
Summary: Sit back, relax, and gobble bubbles. I thought it was supposed to be relaxing, but it's a stretch to classify some of the levels as casual. A great game to play when you are in an alcohol induced stuper.
Summary: Osmos. Look very relaxing. Nope, nothing more WRONG. All this relaxing and calm environment turn to s*it after few levels. This game is hard as hell... normally i would count it as a plus, but in Osmos difficulty level is bit too high. Well, it's all about absorbing bubbles to make bigger bubbles.
Summary: Very relaxing and beautiful, but I found that each level started out really hard, and I'd have to reconstruct the level a few times to get myself off the ground. But once you have, the ball is rolling, and it's then fairly difficult to lose unless your attention lapses.
Summary: You might rate Osmos low if you haven't tried enough of it's features; or, as a Casual Gamer, possibly overated. I'm not a full-time Casual Gamer, but enjoy them occassionaly. Osmos is an Indie game. That itself should warn all buyers it's probably going to be a unique game experience.
