IO games are relatively easy to learn but very hard to master. They can be considered an MMO, where you have to grow your character by consuming some sort of a type of β€œfood” and by defeating other players. You play with numerous other players, so watch out. As Qui-Gon Jinn says – there’s always a bigger fish, or in this case – a snake. You may fall prey to the bigger ones, which means game over!
