Day 2
Sadly, today has been very unproductive since familiar issues have kept me far from my computer all day.
But there was progress: I was able to work a bit on the resource spawning algorithm, now the resources have a rarity value that affects how much and when are they spawned. Also empty planets will generate new resources with time.
I also fixed the planet spawner, so they don't overlap anymore and the placement is a bit more clever...
And I broke everything a few times when doing so (warning, flashing lights)
