Solid concept, some issues.

Some gameplay elements are a little rough, specifically the strict time limit coupled with the randomness of the objective positions; the time crunch also makes it hard to make use of the shop. Overall I'd recommend either lengthening the amount of time available, increasing the time rewards for deliveries, or pausing the timer while in the shop.

Controls are really unintuitive. The ship seems to lurch and gain speed left or right really quickly, making it so the most effective way to move around is really slow and cautious, which can feel a little tedious.

The background image moving around was a little distracting. Not a huge detail but I figured I would mention it.

Some collision seemed off, luckily not in a way that hurts the experience. Like I was able to partially clip through walls without taking damage.

haaard. Also, needs an option of holding up arrow instead of pressing it constantly, not really convenient and feels weird that this rocket engine only works in short intervals
