Core Miner is combat-free space mining game. It is a peaceful experience and allows you to take your time to explore a procedurally generated world and search for valuable minerals to sell. You take on the role of a regular industrial worker trying to make a living – no, a fortune – doing the risky job of mining in the Core. This game is a solo indie project.
Good old nebulae.
I like nebulae in space games. I was considering adding another one. I've got to pick a colour though.
