This month's goodies.
Mr. Mahjong Touch -- Mahjong match fun.
Undercroft -- retro-style turn based roleplaying game. Anything by Rake In Grass is good nowadays.
Turn Episode 1: The Lost Artefact -- yes, the developers spelled it that way. So if you are looking for it in the appstore, it is this title. Very cool, but battery draining turn-level puzzle game.
