Amazing Concept. I love the fact that you have to drag tools over the stuff you're interacting with. The game feels smooth and natural, though a lil slow at times. I think something that could be done to improve it is, when you pick up a tool, whatever is on the screen the tool can interact with glows a certain colour, or has some sort of visual indicator.
I feel like the game feels like your in less control cause of the fact that you have to drag your tools. Though I also see what you mean by time.
The visuals though minimal are super sleek. So, ye :)
