I was surprised how challenging this game is. I played on "Easy" and I still struggled the first couple of times.
The visual feedback on the rocks is fantastic! It was fun to mine like a madman and rush back to the ship.
My main problem with the game is the oxygen system. It depletes REALLY fast while moving, and combine that with the floaty physics and the tendency to get stuck on blocks' edges and it gets extremely frustrating. I'm also not a fan of how the timer still counts down while you're in the ship trying to decide on upgrades. I did panic and buy an upgrade that set me too short on Yolkium to advance to the next level.
Overall, solid game with great juice in the visual and audio departments.
