Wow this is super impressive! For the limiting time this is awesome! The atmosphere feels great and consistent. the movement feels great for a spaceship and destroying enemies also feels super satisfying. The variations in enemies are awesome and the different planet types are cool. If you ever plan on continuing development on the game having some upgrades (even if small) to manage would be fun! Also, while I am still trying I never got to the second ship yet :(.
One way to maybe fix the getting hit on the planet issue is maybe make it so any ship that spawns with a planet has to be defeated before it can be entered. idk if that would feel right though
