Limaxio is very similar to another popular IO game Slither.io. In Limax.io players are in charge to control cute luminous slugs and make them fatter and fatter by eating colorful orbs, scattered all over the map and other players.
In this game, you can freely move through other players and hit them with your head. To kill other slugs you have to accelerate and let your opponents hit the colored track you've left behind. Only your boost trail can kill other slugs.
