The visuals are amazing and the soundtrack which is also great reminded me of Machinarium. It also appears to be dynamic, which is impressive. Overall, the game already seems really polished for only 7 days of development.
One thing I would criticize is the lack of an actual incentive to take risks. At the moment, there isn't really a reason to go faster or to take on more cargo except for intrinsic motivation to make the game harder for yourself. Maybe you could have cargo expire, so the player has to strategically choose when to best accelerate the ship.
All in all, a great jam entry! I enjoyed playing it.
