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.
indiegames.com

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.

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.

Beautiful, simple, sweet, great soundscape. I seriously doubt you'll be dissapointed with this one. It does have a short lifespan, but you'll enjoy the trip (kinda like Portal 2, but more "ethereal"). Worth the money!

You remember the first evolution stage in Spore? Someone decided to make a full game out of that and it surprisingly ended up being pretty good.
You start off as a little cell in a large map and grow by absorbing other cells, but to do that you will have to move, which costs a bit of your own cell, depending on your current size. Continue to grow until the game says "all right, that's enough, you can move on to the next one now.". And that's about it. There's a couple of little gimmicks here and there and different gravity every now and then, but that's about it. Critics often say that Osmos is a very relaxing and immersive game. Immersive, yes. Relaxing? Hell no. Once you get to the harder stages, the game starts getting pretty frustrating and relies on some luck under certain circumstances. During some of the last stages, I was moving myself very carefully, hoping to god that I wouldn't get killed by one of the larger cells that was barely a pixel away from me. So yeah, claiming the game's relaxing is a lie to the biggest degree.
As for the presentation, I like it. All the cells look great and filled with little details when looked at from up close, but as for the backgrounds, they're basically non-existant. Not that I have a problem with it, considering you're going to focus on the cells for 99,98% of the game.
If there's one thing that Osmos is known for, though, it's without a doubt the music. The OST's been praised for being, wel... good. And in this case, I can't deny the soundtrack's pretty damn good. (even though it really doesn't fit in with the player desperately hoping things don't go horribly wrong every stage)
Overall, Osmos is pretty fun, but for 10 bucks, I can't recommend it at that price, but if you can find it on a sale, I'd definately recommend picking it up then.

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

Osmos is a game about particul's life, growing by eating other particuls ...

Nice music, relaxing game, playable in my browser (bought on humble) and increasing difficult.
Played before buying on steam, and it's really a nice game

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.

Just as others have said, the difficult stages feel random and not like puzzles to be solved.

The gameplay is frustrating, due to the way movement works. You're supposed to move carefully and are punished for changing directions, which isn't a very fun gameplay mechanic. In other words, you're playing this game at its best when you're only making small corrections to your movement instead of big changes, so you're forced to be patient. You can speed up time if you don't want to wait, but this can result in you missing stuff because you aren't observing your movement as carefully. It's an interesting idea but somehow it just isn't very enjoyable once you get to a certain level of difficulty. I found myself at that level within the first few stages. Instead of being motivated to try again, I just got frustrated and quit because each attempt involved lots of patient waiting and observation. It just feels like it's trying to waste my time, and there's better games that give me more enjoyment per second, waiting to be played.

A very interesting and extremely challenging game, but all you do is left click. If you love left clicking being the only control and clicking a ton, you will love this dumb game. Pixeljunk Eden is the only game I can think of that is even remotely similar to this but I thought it was a good comparison to say that Pixeljunk Eden is a thousand times better than this zzZZZzzZZzz-fest.

This game is very casual, rules are very simple, and the physics are straightforward. Some very interesting puzzles from some very simple rules.

On the earliest levels it's more of a puzzle, but later it becomes clear. This _is_ what Spore _should_ have made the first primordial life level as. This plays perfectly - but it's more challenging than Spore could afford to make their game (because they were making a game targetted at 5 year olds - but marketted to adults - and Will Wright no more pizza for you, but I digress).

Because you're ejecting your own body weight in order to move, the game is seeing whether it's worth sacrificing size for speed in order to eat other bubbles, and also to avoid bubbles that are big enough to eat you.

OK, everyone knows the game spore right? Right. Well my favorite part of that game was the cell stage. This is like the cell stage of spore but it never ends. Very fun game, albeit difficult but very fun. I recommend it to anyone who can relate to this review.

You were the "good at that web-browser game, Fishy, guy" in High School. It's been a while since you last had the luxury to zone the ♥♥♥♥ out and mess with some stupid ♥♥♥♥ of the underwater variety, but, in from the rain, Osmos drunkenly stumbles.
He slurs, "Y...I-I fff...♥♥♥♥ing remem...ember you!" A breath.
You don't remember him.
"I w...was always butter at Fishy...th-than you!"

You contest Osmos. But Fishy is a different world than you left it.
You can't lose this descriptor of indescribable importance, this life-defining title! You are the "good at that web-browser game, Fishy, guy"!

As you extend the ropes into Osmos's damp, squishy depths, you reaffirm your ideas of yourself as a patient individual, capable of persevering in the face of a challenge.
But as you lose sight of that purple sphincter and are drowned in ambient music and a heavy blue palate, you realize that Osmos wasn't drunk those eight hours ago. He's just a snaggle-toothed, half-♥♥♥♥♥♥♥♥ ♥♥♥♥♥♥bag.

And I've come to thoroughly enjoy this "puzzler", which, steeped in millennia of the old gods' hatred, is utterly unforgiving and luck-based, altogether betraying its image as a "zone the ♥♥♥♥ out and mess with some stupid ♥♥♥♥ of a microbial variety"-kinda game.

This game is broken. It's fun and simple then out of nowhere comes a level that I spent 3 hours trying to beat and failed.

I must admit that this game was sitting in my library collecting dust before I started playing for the first time.
The only regret I have is that I've waited so long to even begin playing.
I got this from one of the first humble indie bundles.
I can't really explain much about this game, other than it's worth a try if you're into relaxing puzzle games.
Although the last few levels on each tier are more frustrating than relaxing though.

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!
