I liked it. The engine was the best part - I can really see it being used for a lot of things. Unfortunately, I felt that the level design was a bit... sparse. I don't know, but it all felt rather samey to me. Maybe that's the angle they're going for on this level, but as a test and the only thing I have as a benchmark, it felt rather abandoned. I did like the music, though, a lot, and I haven't got past the second boss, so I only have videos to show me how interesting Act 3 is. Wow, literally?
