Most players start by taking an action to reveal a room of the dungeon. In this case the tile is turned over and the object/character tokens are placed. You get to place everything you reveal except for your own objects. Where things are placed will make a huge impact on how the game is played out. See how the Goblin is trapped in that dead end section of the room? Your opponent will love it when you do that.

You can also use an action to move a character up to his or her Speed. When characters move over objects they can pick one up and carry it, using its powers.

Also, that space with the circular arrow in it offers a powerful opportunity that gives this game its name. A character there can be used, for one action point, to rotate the room 90 degrees in the direction of the arrow. As it says on the box, "The easiest way is always twisted!"
