Nice concept. At first I did not know that you had to restart multiple times so that you earn money for upgrading and use it to upgrade the ship. I feel like players need the tutorial for that or a notice.
I was also hoping to escape the gravity earlier and float around and upgrade the ship in stages, because it seems repetitive and long to me to lift off multiple times and upgrade the ship every time.
I love the cartoon animations, they bring a vibe to the game.
