Reminds me of MotherLoad flash game. Nice idea with color-coding materials, although pretty hard to see blue text over black boxes. Was able to "exploit" facing sideways while ascending/descending. Died of overconfidence and greed. Character could be a little less sticky to surfaces. More upgrades would make it a lot more addictive.

There's practically no gameplay, although I found myself wanting to continue for some reason. I could see this become a nice little idle game.
