I NEARLY finished plaything this.  NEARLY.  As a tech demo it's actually really cool.  I love the procgen world, it's really something else for a game jam game.  My problem is the requirements to build the ship being so high coupled with there being no background sound, music, nothing like that, quickly turned the experience into a nightmarish slog of searching for resources.  I could not cross this finish line, unfortunately.
One other gripe that would go a long ways:  make the player capsule skinny.  Like, very skinny, or activate a second collisionshape on jumping and and a wider one when falling.  Jumping upwards is just...not fun at all.
For what it is, though, it's a great little demo.  As a longtime minecraft player (I used to play a lot more than I do now) I found myself getting to scratch that old itch for a second.  It was nice.  Thanks for giving us a game to play!
