I did have a few more ideas, specifically about how the difficulty system could be expanded upon.
Currently you can only change the speed of the game, but I think it would be neat if there were lots of different settings to change to affect the difficulty, plus 3-5 preset difficulty levels. Examples of difficulty variables might be the speed at which new space stations turn up, the speed at which the timer ticks down on new stations, the rate at which unique stations appear, whether stations can generate 1/2/3 shapes, the timer length when the space truck overflows, or even the base size of the space truck.
For example, "Hobbyist Mechanic" might be the easiest, where the truck can hold 5 items, the timer when it overflows is slower, unique stations appear less often, and stations can't generate more than 1 shape each, but "Galactic Systems Technician" might only let the truck hold 3 items, it overflows a bit faster than normal, and unique stations appear much more often etc. Then there might be 1-3 middle grounds with appropriate space-themed nanes, plus the option to fully customise the settings
