I like it! Only thing I would change is to have the lights reset when moving to the next stage.

I originally had the lights refill when moving to the next stage but the levels felt too easy and made the oil pumps a little useless. Perhaps if I had more time to design the levels so there's actual strategy and puzzle solving involved. A lot of things were very rushed at the end of this jam.
Thanks for playing though!
