Whoop! A puzzle game!
No lie, I love puzzles. This reminds me very much of my game Cubus that I made for GWJ 37 except you added some nice touches with the portals. I will steal those ideas for my next game - lol
My only suggestion would be to add some music in there. Just to build up the atmosphere a bit more. Another tip is to create an audio bus for sounds effects and add some reverb on it. Mind you, I might overdo that in my games!
Solid puzzle game, maybe the theme was a tiny bit weak in that a robot that doesn't do what you say sometimes is not the most exciting malfunction. perhaps it could have a some kind of time-based mechanic where you have to "hit" a sweet spot to send a control signal at just the right moment or something similar.
But again, a great little puzzle game and I'm happy to see more like this
