After collecting 24 cubes in Fez, I'm already kind of bored with it. I heard it get's interesting after 32 cubes, but I don't know if I'll have the patience to track down the others. The map is a mess and not particularly useful, which doesn't make things easier. The game really doesn't offer you much help or hints at where to go next at all. Some people might like this fact, as it seems more "retro" that way, but I'd prefer a more guided approach. It starts to feel more like "work" at a certain point. Anyway, glad I waited for a pricedrop on that one... just wanted to add my 2 cents.
As for the rest of the sale, I'll probably end up buying Bully along with perhaps the Walking Dead if the price is right. Already picked up Mark of the Ninja and Dust.
I agree with you fully especially on the work part. What really makes it work is that every time you go up a level, or enter a room, you godda flip flip flip, ah nothing there, rinse repeat. At first there was a wow factor, but as the game chugs along it starts to get monotonous. And your 100% correct, the map is garbage, bout the only thing it's good for is letting you know you missed something. Feels like he just made a bunch of levels and then said "let's put a warp through this door for no reason." I do like the concept of it though it's a slight rip off of the psp game crush or echochrome. Anyway like you I am glad it only cost 400 ots.
