Fun idea! The music is a great fit.

I ran into two issues:

• It was hard to drop the oil in the tank without getting stuck in the tank myself. Maybe a drop zone in front of the tank?
• I kept picking up the wrong resource by accident when it spawned right in front of me.

Did not manage to build the rocket in time.

An idea to make it more interesting - you could have a machine that turns the oil into fuel and one that builds the rocket ship. They could have an input stack of resources that you can refill and work over time. That way, it adds a bit of managing the machine to make sure they don't run out of resources. You could even have the produced fuel as a third resource, requiring the player to carry it to the rocket tank. Maybe the rocket building machine also needs fuel to keep working. By adding just a bit more complexity I think you could make the game more interesting.
