Could be okay eventually but requires a lot of work. No snapping of conveyors etc in the base, and it's not clear at all which percentage of purity gives you what value. Also, all the upgrades are versions of the same thing with different percentages, and some of the stuff simply feels useless at the moment. Maybe it'd be helpful late into the game, but then I don't understand why you need a mid-tier version. Also, you can fly with cars if you pick them up while standing on it. The map is also pretty plain, giving you little reason to explore. It doesn't even say anywhere how much each resourse is worth, so if it's beneficial to go out of your way to get something further away. If it is, then why would you get anything nearby?
