A very cool game, it's soo satifying to just drill around the planet once you get to it.
It's super fun to construct your own drill and try out a bunch of different stuff.
I ran into a problem thou. As i left the first planet i wasn't able to build a crafting bench, which i think should always be possible if you have the resources.
Then i encountered a bug, where the game would start to lag really bad as i threw out 5-6 full stacks of dirt and stone, which made it basically unplayable after that.
I think you should expand this, add sound and animations and include stuff to craft for all the different materials that are already in the game.
