This was amazing, I can see why you'd go for a steam release!
It took some time before I realized you could upgrade mid flight, and cause of that I didn't understand what mining did until later. But the game was fun enough without me knowing how that worked so I kept playing and eventually got it, then it felt really great and fun! Love the aesthetic and I unlocked all the parts. I though that expeditions were gonna take longer and longer but I get why you don't want that during a customization jam, it was the right choice.
