Hi, thank you for playing. I had less time to invest in polishing. The ending is triggered when the planet fully grows and the player goes at the hole. Since the losing end is more on the decay theme, I invested less in the winning one. The pulsing sign on the ground supposed to be the planet's wound. Bringing those spherical plant made thingies and poking them above it should heal it. Then the ending would still be triggered at the hole.
Glad you enjoyed it, I had the same Outer Wilds feeling while creating it. The entire gravity growing system took me more than I expected so it stole time from the polishing side. I implemented like 20% of the sounds and effects I had in mind. Same for the loop design. But happy I finished it.
