a beautiful, absorbing experience… brilliant to look at… the best videogame music I've heard… will make you forget your cares and immerse you in the game… you'll find yourself returning for the experience. 8.5! Editor’s Choice Award.
IGN

wonderful gameplay… beautifully polished and tantalizingly atmospheric… Osmos mixes puzzle, action and strategy remarkably and all the while does it with great finesse and style.

beyond doubt, a work of genius... a relaxing, meditative experience about going with the flow... It all adds up to something otherworldly and just . . . incredible.

an almost transcendental video game experience… a stellar example of electronic music's potential impact on indie video game production.

The principle of this game is fairly easy: you start off as a small sphere shaped object (I call it the “cell”) and seek to be the largest object on the rectangular shaped map. The rules are simple: if you touch a cell smaller than you in dimensions, you consume the counterpart and grow larger. If you make contact with a larger object, you will be consumed. You can move only by discharging mass from within your cell in the opposite direction you wish to move along. The repulsive force will accelerate your movement. Of course this will make you shrink and be exposed to new threats. So you better not waste too much mass. You are given only one tool and that is the control over the pace of time.

While the rules are readily comprehensible, the gameplay might be a challenge. There are modes where you are concerned with finding the most economic “route” of consumption from a logistical point of view. In another game mode you will find AI controlled opponents who try to grow large as well and eat you before you can eat them. Lastly, you will find a game mode where the organisms are organized like stellar systems – these maps ultimately require basic knowledge of orbital mechanics in order to be mastered.

No matter what game mode you choose, basic knowledge about mass, force, acceleration, velocity, momentum and gravity will come in handy. I wouldn’t say that this is strictly a physicist’s game though. I am sure the game is also fun for people who play it by intuition only, I would recommend it to any puzzle solving gamer. There are an infinite number of maps - each time you beat a map a harder one will be generated, what a perfect challenge!

Hemisphere Games is a Canadian developer company that released Osmos back in 2009. They give you the opportunity to control a... well... cell. You need to find other cells that are smaller than you so that you can absorb them and grow bigger. This concept, of course, also means that you need to avoid bigger cells until you are big enough to absorb those, as well. If I remember correctly the criterion on each level is always to become quite big (not necessarily to absorb all the cells on the map).

I like how you need to proper yourself ahead to gain momentum - in the process you are losing matter so you cannot really do this forever as you are gradually becoming smaller. Patience is a virtue!

There are several levels and all are part of 3 major zones - each require you to follow a different playstyle and some of the later levels can be pretty challenging.

The game has an excellent soundtrack full of ambient tracks. They accompany this unique gameplay perfectly. I believe Osmos is one of those indie games that is a must-have.

The amount of time I have in this game is minimal, but it's been such a great experience so far...so I decided to write this review right away! With the physics of propulsion, and the fundamental aspect of Predator vs Prey and the food chain, this game is great for getting kids engaged with basic physics. As a teenager however, I thoroughly enjoyed this game as I was introduced to new vocabulary such as 'biophobe' and more. There is seemingly no story-line (which is not a bad thing in this case). I absolutely love this game and recommend it to everyone! At first, this did not seem like my kind of game, but venturing further, I can say that I absolutely love this game.

10/10 - Great job

This game acts like a "zen" experience, with the soft soundtrack, simple controls, uncluttered aesthetic, and relaxing gameplay inherent to the genre. Games like Flow and Thomas Was Alone come to mind. But when you play the game, it isn't like those games. It's brutally difficult and incredibly unforgiving. A typical level will require you to quickly capture one or more enemies much faster, more maneuverable, and all around superior to you in every way, before they grow to large to defeat (which takes only a few seconds or a couple of mistakes from you to happen). But the failure state isn't immediately obvious, so you often waste several minutes trying to struggle out a win (and sometimes you luck out and get it).

Play this game only if you like extremely frustrating, zero-margin-for-error physics simulation games with no plot, minimal gameplay variety, and a significant luck element.
