From the developer
Control a cute slime and become the biggest on the map! Search for slimes of the same color and merge with them to grow. Once you collect all slimes of your current color, your color changes and a new hunt begins! Be careful: if you absorb a slime of the wrong color, you lose one of your collected slimes. If you have none left, the game is over and you must start again. Simple mechanics, bright visuals, and addictive growth gameplay!
