Oh this is fantastic. I love change-of-perspective stuff.
I super dig the aesthetic; it didn't even occur to me that everything is straight up untextured until I'd been playing for several minutes. It works really well! The most important things are the text and the chemicals, and they both stand out about as well as they possibly can like this. It's a cool aesthetic besides, and drives home "sterile lab" better than any sterile lab textures could.
I can imagine a whole series of different lab setups you have to navigate, with different lab equipment and hidey-holes and maybe even places you deliberately can't get into until you get small enough. You've got something really slick here; run with it, imo :)
