From Enemies and Ragdolls

This update introduces enemies into the game. In order to find them just enter the dungeon. You can fight them but be aware: they will fight back! Once one of you is defeated the character will turn into a ragdoll.

Don't worry if you die - the game will send you 6s later back to the main island.

Hint for the dungeon entry: Go to the north and stand still in the "mystery cube". Thats the entry for now ;-)
