This a great little game, you could say it's one of those hidden gems.
Although the playtime isn't that long, the visuals and music is incredible for a game that (most of the time) only costs 1$
You play as a small microorganism climbing the evolutionary ladder by eating one of three microelements:
-Red which makes your Sparkle (as your species is called) faster and more manouvrable, however at the cost of eating speed.
-Blue which makes your sparkle more balanced in the way of movement and eating speed but sadly looking quite uninteresting.
-Green which makes your sparkle incredible at eating with the highest eating speed and a skill that makes your mouth about 5x bigger, however it isn't very fast and his turning speed also ins't too great. However the green sparkle is in my opinion the best looking sparkle.
As you grow more and more instead of eating stationary microelements you start encountering species, most of which have ways of stopping you eating them often in the form of a slow trap. others take a long time to be fully eaten and until they are they will keep pushing you a level upwards if you touch their head, and others are relatively peaceful but require you to find a way into their body to eat their guts and finally decapitate them.
Each stage of evolution your sparkle evolves visually, at first growing longer and developing a type of sac to show you its road to the next level by the size of it, after that it will grow jaws or in the case of the omnivore it will grow even longer, after that evolution truly branches and every sparkle will go it's own way, i will not spoil this because they look too beautiful to explain.
Though the levels are few (there are only 14) there are 2 optional boss battles, The Squid-Worm and the Octury.
The Squid-Worm is a large worm that requires you to eat all of his segments before eating his head, not too hard but it looks great and it's a fun way to show yourself how far you've come in your mad dash to become the top species in the sea.
The Octury is a humongous octopus that will make you eat all the glowing orbs on it's tentacles before entering it's head and devouring it from the inside out, though -once more not very challenging it's a huge monster that is great to look at in comparison to your little sparkle.
This is a great game and if you like Flow or need something relaxing in your library i definitely reccomend you to pick it up, it's very cheap and there are even trading cards to be gained.
