I played to the end, and I think it might have been more enjoyable if not for how it was never possible to tell what was a wall and what wasn't. It really became just push arrows and hope for the best. And the level with warped controls was kind of frustrating.

You put an interesting twist in it. I came to expect one thing, then you changed that. It was an interesting game.
Also, that warped control level was pretty lame.
