In Osmos HD, players take control of an energy ball. The game goal is as simple as it is ingenious. You simply absorbed as long as all other (or specific) energy balls until you yourself become the largest. However, although the gameplay in the core is very simple, so the game still has a certain depth. Thus the energy ball can not directly control. If you want to move them, so you have to tap behind the ball exactly counter to the desired direction of movement. Here, however, the ball loses with each acceleration energy and shrinks. The faster the ball moves, the faster it will shrink so. So you have to very careful handling resources. Furthermore, it applies specifically to evade antimatter bullets and some of the balls to be absorbed also take to their heels, or absorb other balls in turn.
Graphically, the game presented perfectly. The animation work attractive and liquid and the framerate is very smooth on the Kindle Fire HD. By constant scaling between microcosm and macrocosm, the appearance is also very varied.
The soundtrack of the game unfolds a wonderfully relaxing Atmophäre and lets the player dive fully into the action. The high price is the face the quality of the app completely justified.
