SnowHeroes.io

Ho ho ho! Merry snowing!

SnowHeroes.io is a competitive growth-based arena game. You play as a Snowball constantly rolling through a field full of snow. All the time you move, you keep growing bigger. 

Absorb colorful orbs and other Snowballs smaller than you to grow even bigger!
Whenever two Snow Heroes collide - the bigger one absorbs the smaller one. So avoid those larger than you and strike on smaller ones. 

But note - there are some obstacles like trees, rocks and snowmen. If you hit one, you lose a significant amount of your mass, so be careful.
