This is very unfinished so you may run out of things to do. Everything that is in the game should work though.
Some things that might not be obvious: - brighter yellow means more oil, but size matters more. A big and dull oil field is much better than a small and bright one. - so try to find a lot of yellowish squares all touching each other. Diagonal touching counts. - oil rigs pump faster when there is more oil below them. - click once on the game to make keyboard controls work.
