Really good! I enjoyed the unique attacking mechanics, and the surreal nature of the world. I got very lost, and eventually ran out of time, so a map might have been nice. But at the same time, getting a bit lost isn't the worst thing, and it certainly adds to the feeling of time pressure, so maybe it's best without!
Usually I don't really like time limited games, as I like taking my time walking around and exploring, but reading your comments here, I agree that it gives it a certain novelty that I think I like.
The big problem with it is retaining players into a second attempt; e.g. after running out of time, I didn't really want to do everything over again, so I just stopped. This is where a map may have been useful -- giving you additional tools to skip the parts you don't want to waste time on. But there's a give and take there as well, so who knows.
Anyway, very intriguing; I may come back to finish it after playing some of the other entries. This is really solid -- good stuff!
