Interesting concept, however the shop wasn't working for me (or I didn't get how that worked), so all I could do was to travel until run out of money.

Sorry, in the rush to upload the game, I forgot to create a tutorial on the game's page. The shops should only work if you're on a space station. Originally, traveling to a planet gave the option to collect free items, but spending more time and purchasing items at space stations would make it take less time to get there. Unfortunately, time only allowed me to implement the space stations.
