A strange name for a strange game, Oh Hi! Octopi! is an arcade/puzzle release from the creator of 1-bit Ninja, kode80. Combining single-screen levels with matching-type gameplay and purposefully obtuse controls, it can be a maddening experience trying to learn to play the game, let alone actually accomplish something. But once you do, it's a great feeling, and you'll finally be able to say a hearty "hi" to those little octopi as you smash them with a hammer.
