Art Style: NEMREM released for the European DSiWare store today (500 points), so I'm guessing we'll be getting it on Monday.
I have two of the Art Style games: PiCTOBiTS and AQUIA (guessing at the apparent random capitalization). Both are decent enough for $5 each, but I'd say PiCTOBiTS is the better choice; sort of a combination of Meteos and Dr. Mario with an 8-bit skin. No idea what this new one is about.
I must say the Wrath Gate achievement and quests....best thing they've ever done. Totally caught me by surprise. They've made questing fun instead of a grind. I don't know how they can possibly top that though.
