I would definetely go as far as to call this a really good entry; I enjoyed the very 'robotic' feel of all of it (well, the music was a little jarring) and the storyline. It was a little tricky for me to get used to the controls; it could just be me, but the squeeze/crouch buttons seemed like they were in unusual spots. I also noticed a bug where if I hold the down arrow for long enough, the floor goes out under me and I can see through the world. Despite these pretty minor pitfalls, I really like this idea and it was executed very well.
May I have a rate as well?
