From the preview:
"What we've played seems promising, though it isn't without a few issues right now. For one thing, the perspective stuff doesn't always work exactly as you might think, though this may be remedied through practice. For instance, while two offset platforms might be able to connect in one instance, they might not in another. As well, it seemed a little touchy with regards to whether or not your character would land on a platform after falling if he was close to, but not quite behind, another piece of geometry. The second level required that we fell through one hole and onto a platform on top of the level, but it was short enough that lining up the fall was a little tricky."
