Piece together spaceships to meet the criteria of your customers. Very simple in its idea, fairly simple in its execution. Fuel requirements? Add enough engines. Need to haul cargo? Add a cargo bay.

Sunshine Heavy Industries puzzles are very minor in their challenge, there are a few roadblocks to navigate - thrusters need fuel and cooling, weapons need a power source etc. - but nothing too overwhelming.

The smarter you are with your design the cheaper you can make an adequate ship for the same payout, but again this is a simple task - and arguably the more difficult and interesting challenge is to make a good looking spaceship in the process!

It's not a bad game, I enjoyed piecing together 2D ship parts for an hour, but ultimately the lack of challenge makes Sunshine Heavy Industries a little too repetitive and little too quickly.
