Such a wonderful game. Physics logic puzzle. Zen levels and soundtrack. Very careful use of acceleration required... Don't click (accelerate) without thinking. One click too much can mean the difference between life and death.

Osmos is a wonderful and calm experience - as long as you have a lot of patience. You play as a little mote absorbing other motes to become the biggest in most levels, or aiming to absorb specific motes in others. You expel a bit of your mass in order to move, so much of the game is based around trying to be very specific with where you move without expelling too much of your own mass. The game has a very zen-like atmosphere, with ambient music and cool colors, so it's easy to assume the game is very relaxing. But don't be fooled - some of these levels are absolutely brutal. The game features a speed up and slow down time function which helps with the patience aspect, but there are plenty of times when you'll be speeding up just to have to make a split second movement decision and instead propel yourself right into something bigger than you. The most challenging levels are the orbital levels, or the "force" section of the game, where your mote is orbiting around something larger and you have to figure out how to move while still attached to your orbit. Some of the later levels require you to move from the orbit of one object to another and then back again. This was a very hard concept to wrap my head around and I spent hours on just the last level of the game, patiently gathering mass, switching between orbits, only to die by unfortunate timing or expelling too much of my own mass to absorb anything else. It was a massive challenge that felt very satisfying to complete, but there was absolutely some frustration and headache along the way.

Great game. I got it on mobile first then here. The simple take on the "eat smaller thing and become bigger" game loop popularized by a nearly infinite amount of browser game gets a simple and gameplay changing twist. You have to expel/spend your inner mass, making yourself smaller, in order to move. Genius. So much fun for a quick session in the morning to start the day.

An absolutely unique game, unlike anything else. The only downside is the extremely difficult maps at the very end. But some levels are so good that I replayed them 10+ times.
