Just got Anthill - it's february, but i'll say it: Game Of. The. Year. Great garphics, cool concept with demanding levels (defend your anthill against funny and menacing bugs, use four different and funny types of ants with different capabilities), witty gameplay. And you can play it again, and again, and again, it does not get old.
This is (really!) a kind of meditation. Chilly soundtrack and a completely new form of game: You get some forms and have to roll a string around it in a way that most of the object becomes covered in a new colour (that happens wherever the string touches the surface of the object). The level-screen itself is a beauty (you climb a tree with lanterns). It's just a great game.
Buy it. Trust me. I bought the first chapter when the two guys behind "World of Goo" made it available (for PC) and then went for the full treat. Brilliant concept, handpainted graphics, innovative leveldesign, funny story, funny creatutes, great soundtrack. Fun. Now go spend some bucks. It's completely worth it.
EVER is a big word, true. But this is, at least in my view, the greatest iPhone action game EVER. Cool designed graphics, a brillant concept, some clever variations of this concept, humorous text-messages, great soundtrack, immediate addiction, months of fun. Good Game.
