This put a smile on my face. I immediately got the Portal “test subject” vibe. I was starting to mentally collect some of my thoughts about the puzzling and how to phrase a lack of story, when I saw the cheeky cracked walls - and then the humans running around with the siren, ha got an out loud laugh from me as I made my way to the end of the hallway with some carnage along the way. Sort of felt like a classic “distract you thinking one thing, when it becomes another”.
On the controls and behavior, I would say it felt awkward being only able to face left and right, and the red robots being functionally no different from the red blocks (not attacking or anything) felt a bit flat. Also the move and slide not being able to fit into 1x1 tile spaces made it feel a bit unpolished, though not a problem to work around.
