You are summoner extraordinaire in Diluvium, a small game that arose from the TOJam game jam earlier last month. You summon animals by typing in their names, and you can create a totem pole of up to three animals. There can only be one of each animal on the playing field at once, and the point is to destroy the enemy summoner.
Hundreds of creatures are available for summoning, most beautifully illustrated. Some of these include what seem to be easter eggs -- like Meat Boy, or Gomez from Fez. I think I saw some faces pop up while I was playing, too -- the developers, perhaps?
Playing against others is highly recommended, though a local mode is also available. Check it out here.
