Hi! I really liked your game! It was easy to understand, fun to play, and fit the theme of the jam really well. I liked that I could upgrade things and discover new planets, and the art style was really good.
The only thing I didn’t like was running out of bullets so quickly, haha. I had to return to Earth quite often just to collect resources.
Maybe you could add multiple extra missiles, and later on, an automated asteroid catcher as an upgrade. That could make the progression even more interesting.
It was really fun playing your game , I really enjoyed it! Great job!
