I enjoyed playing this game. I like simple puzzle mechanics and emergent complex gameplay, level design is good, mechanics are various but all intuitive, and visual style together with music and sfx is solid and very appealing. I think that If you went for the theme, you should've considered making environment more green to convey feeling of micro-electronics (if that's the legend), as now it feels more like human-sized robot fixing mech-tech facility. Despite that, great game, well implemented, very well polished, great job!
