I'd also like to say that while Dewy is far from perfect, if you can overcome the somewhat finicky tilt controls, it's a worthwhile game, especially at a low price. It's got challenging levels, (mostly because you'll fall down with the controls some, and you have to start over from the beginning when you die) a beautiful visual style, and in-game advertising during the loading screens!
I recently beat Alien Syndrome with my younger brother co-op, and the best way to describe it is some sort of Diablo-esque (it's got random loot stats, so you're constantly choosing between items to determine what to keep) in space, but with guns, and dungeons that aren't random, but are somewhat reptitive and big. There are 40 levels in all, and each will take about an hour to beat. When I say repetitive, I really do mean that. The monsters spawn for a long time, and it takes forever for you to get out of the first space ship. The game is about 15 levels too long in my opinion... so since I estimate it's about a 40 hour game, it's probably 15 hours too long. If you play co-op though that does ease some of the pain if both players are fans of this type of game.
Harvey Birdman would be five bucks under this deal. That's not a bad price for a game that has one or two interesting cases, but essentially amounts to being a Phoenix Wright-Lite. Harvey Birdman, despite being completely voice-acted, and delivering on the show's humor and character, really makes you appreciate Capcom's meatier and more expansive writing in the Ace Attorney games that much more.
