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.

This is another one of those games for which the designers think they can make it fun by making the controls frustratingly hard to use. The price is ridiculously high too. If you do not mind getting frustrated by really sluggish responses to controls, and paying through the nose, then it can probably be fun. I personally cannot stand games like this.

Osmos is based around a fairly simple concept. You are a mote. You propel yourself by shooting out part of your own mass.
You get absorbed by motes larger than you. You absorb motes smaller than you.
On every level, you are attempting to grow much larger.
There is a time control mechanism allowing you to speed up and slow down how quickly time passes. This is essential.
Why you may need to speed up time: You're moving in the correct direction, but very slowly. You could speed yourself up by shooting out more of your mass, but you generally don't want to waste mass doing that.
Why you may need to slow down time: Sometimes things are moving fast and you need to propel yourself in a very particular direction.


Pros
+ Decent variety of levels. For example:
* Entire map covered with motes and the motes are non-moving. You start in middle and have to carefully maneuver yourself around. Be careful! The pieces you shoot out can hit the other motes and start to move them. These feel a little bit like puzzles.
* Orbits. You and other motes orbit around one or more "Attractor" motes.
* Sentient motes. You have to absorb some motes that have some basic AI.
+ The orbit prediction arc. This arc predicts your orbit around another object. You can then see if your path matches what you want. The game would've been too hard without it.

Cons
- Can be very frustrating. You may have been playing a level for 10-15 minutes when you lose because of:
* a moment of inattention.
* you realize you've reached an unwinnable state. That one other mote you need to absorb is just a tiny bit bigger than you. (Note: the game will warn you when the level has reached an unwinnable state. You'll see "Doesn't look good..." at the bottom of the screen. However, that warning is often late.)

Overall
If you're prepared for a lot of frustration, Osmos can be a rewarding game.

Easy to learn, Frustrating and near impossible to master.
Beautifull graphics and soothing music combined with challenging gameplay make this an experience that's worth the money in my opinion.
I heavily reccomend this game, even thought the price might be a little bit high for the amount of content.

Nice, challenging game concept in a similar vein as the .io series. The main differences between Osmos and Agar.io is that Osmos is much more difficult when it comes to learning controls, and it's not multiplayer.

This game is meant to be 'relaxing' and 'chilled out', but really it is neither once you get past the first few levels. If Osmos was hailed as a challenge game, then I might change my recommendation to positive. But even then, the challenge is still largely based on what random mote layout you got at the start of the level. And the difficulty curve spikes massively after the beginning levels, especially depending on which of the three level paths you choose to do first.

The gameplay is similar to agar.io (for comparison), but with more floatiness, so you have to plan out your moves more. It's decently fun, though it will take a bit of time to get used to the movement system. If you are looking for a good challenge, this might be worth a look. But don't expect a relaxing experience unless you have a rediculous amount of patience.

More than a game: more a way of life, a path of zen. Playing this game brings the user a sense of one-ness, a deep connection with the universe, and a realisation that we are ALL the little blue ball, seeking to survive in a hostile environment, but that by joining together (absorbing), we can prevail against all odds.

At least, that's what I tell the people locked in my basement, until they agree to join my cult.

A very ambient game, with a way of making you think as well. Osmos is one of those games that you can just relax to, if you're having a rough day, you can just play the easy levels over again too cool down, or if you feel like a challenge, it also has artificial intelligence that will really make you have to strategize. All in all, loved it so much. If I had to complain about one thing, however, it would have to be the mouse control. I feel limited in how much i can move without becoming too small. That's the only real complaint i can really come up with tho. If you're looking for it on an iPhone or Android, you can find it on the App Store and the Playstore.

First half of the game is really good, if you like calm and tranquilizing games. You can play this while stoned. :D

Second half is utterly frustrating and the cause of the heap of antidepressants prescriptions in this land. xD

When you first start playing Osmos, it's both fun and appealing. However, the later levels increase the difficulty curve far too much. The amount of patience you need to complete some of the later levels is so high that you would need to play the whole level on slow motion and just pray it all goes well.

It's more frustrating than it is fun. Definitely not one I would consider playing unless you have a lot of time to kill and the patience of a saint.

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!

Pre-Release Review
Posted: October 4, 2014
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.

My friend recommended this game because "it's relaxing." What a blatant lie that turned out to be. This is the single most palm-sweat inducing game I've played. It's easy yet challenging and the soundtrack is good. I ended up buying this game on my tablet too.

8/10

This is just another one of those games where your initial response is, "Ah, yeah. This is interesting. This is different. I think I might like this." and that's how it goes for a few hours, playing short sessions every now and then.

Sooner or later you hit the most brutal difficulty curve where your thoughts change from general pleasure to, "♥♥♥♥ THIS ♥♥♥♥! ♥♥♥♥ IT ALL!" and you quit the game and never look back at it again.

Just another one of those games. How unfortunate.

♥♥♥♥ this game.

Osmos is a game where you are a bubble, and most of the time your aim is to become the biggest, by swallowing smaller bubbles and avoiding larger ones.

The game starts off quite easy, but then gets insanely hard. Feraxes are annoying, Epicycles takes forever (with no mistakes allowed), Ambient isn't too bad but quite slow.

Basically it's an inticing "casual" puzzle game that becomes anything but casual once you get past the first few levels.
If you are getting stuck and spending hours on a level, come back the next day. It becomes much easier for some reason, and while the levels are still hard, what was "impossible" is suddenly doable. I have now finished the game (11/11 Achievements) but it took me 18-20 hours spread over 4-5 days.
