This is one of my top games from the jam, I've play this game for so long. It's incredibly polished and has great depth. This is one hell of a product for only 4 days.
My only criticism is I think the player might take a tad too much damage from the asteroids, and I wish upgrading the ship didn't start you totally from the beginning. I would like to keep my current parts. I've had a hard time getting a ship off the ground but it's been a LOT of fun! Full marks from me awesome job!
