Love the vibes! Lost track of time going planet to planet haha!
The steering is a bit tricky, would take me a long time to get the oxygen I wanted. But even then I liked how the gravity of the planets affected the movements. I'd say keep it in but add some visuals to show the gravity's force. Just an idea.
The resources the player can collect can be expanded along with the upgrades and I imagine this game to have the potential to become something big. Keep up the good work!
