Ay?

• Storage Inc - 400 MS points. Many games have been criticized for having controls that feel like a forklift, and now finally that description is accurate. Using the Resident Evil "forklift" control scheme you control, well, a forklift sorting crates into the proper holding areas in a warehouse.
• Shellblast HD - 400 MS points. Shellblast HD has an interesting puzzle concept, but it's marred by the controls. There are two cursors in the game, one controlled with the D-pad and the other with either analog stick, when it would have been much more intuitive to use a single cursor. If you can get past the unintuitive controls though, there's a fun and unique bomb defusing puzzle game there.
• Octagon - 240 MS points. I'm very torn about Octagon. I love the concept of an arcade shooter with enemies color-coded to each of the 360 controller's face buttons. The only issue is that you can only fire in 8 directions. This is an issue because both your ship and the enemies have free movement, so there will hardly ever be a time when an enemy is coming at you from an angle you can actually shoot at. It can get frustrating, but the concept is good enough that the game can't be written off completely. Hopefully there will be an update in the future.
• Pastels Square - 400 MS points. This is a nice puzzle game in which you create colored boxes from lines that fall from the top of the screen. 400 MS points may be asking a bit much for it though considering some of the other indie games available that offer much more for a lower price. But if the price goes down, say to the 80 point range, then this will be a fine download.
• Penguin Slip-Slide Lite - 80 MS points. "Lite" versions of games are tricky. This one offers half the levels of the original (around 100 as opposed to around 200) for a third of the price. At 1 cent per level it's a great deal if you like this kind of puzzle game, but if you do like this type of puzzle then you might like more levels even more. You know, like the original version that was already available.
• デッドラGO! (Deadline A Go!) - 400 MS points. Yet another Japanese game that I don't feel comfortable reviewing because I don't quite know what is going on. This one is a tower defense style game with a school setting and some excellent sprite animation. There's also a masked wrestler at the bottom of the screen yelling things at you. It's a pretty bizarre game, but if you can read Japanese it's worth checking out.

Nay

• Zombies 2.0 - 240 MS points. I love zombies, but this game just didn't do it for me. It's an overhead shooter with a very limited cone of vision from a flashlight your character is holding. I'm sure that this aspect was put into the game to add tension, but the field of vision is so slim that it's really almost useless. Combine the small amount of the screen you can see with the fact that enemies blend in with the scenery, and you've got one frustrating game.
• Arrow Run - 80 MS points. You follow a series of arrows to race across the screen before you opponent (human or computer controlled) does. It's simple, but not a game that you'll be coming back to after the first few rounds.
• A Frog Game - 240 MS points. Jump from one lilly pad to another and eat flies in the process. You can either play a timed game or a game with a certain number of flies. I can't really recommend either.
• Bed Time Nursery Rhymes - 80 MS points. This is a lengthy collection of nursery rhymes, so if you have a small niece or nephew it might be helpful to brush up on some of them. Just don't let the child listen to the game's narration of the nursery rhymes, the emotionless reading might frighten them.
• Dodge These Balls - 80 MS points. A game with a very self-explanatory title. Just dodge the balls as more balls are added to the play field.
• Puzzle? - 80 MS points. Puzzle? is a series of word puzzles including jumbles, anagrams, and several others. If you were playing them on the computer with a mouse or keyboard they would probably work fine, but the Xbox 360 controller just isn't made for selecting individual letters on a time limit.
• Hotel Danger - 80 MS points. Hotel Danger is a memory style game where you choose two windows and see if you get two innocent civilians. You see, there's a killer loose in the hotel, and if you choose the killer and a civilian than he or she dies. Except, instead of relying on your memory the game adds a random element by having the killer move to a new spot every turn.
• BallsAndBlocks - 80 MS points. A ball rolling game ala Marble Madness, but with one fatal flaw: wonky ball physics. I played a ton of this game to try and see if it ever would feel right, but the ball never rolled in a way that resembled real physics.
• クレッシェンドシンフォニー 鏡の騎士 - 240 MS points. This is a single turn-based battle between two young, anime-style witches. Admittedly it's an interesting turn-based style, but it feels like a concept demo rather than an actual game.
• LOLCats - 80 MS points. Is this really what we've come to? As expected this is just a series of LOL cat pictures, most of which you probably have seen hundreds of times by now.
