Thank you for taking the time to play it! I am well aware of the goal not being made clear. I rushed the endings. The marks on the planet (pulsing edges) are not very clear - they should resemble a wound. Using the stick, the player needs to figure out that the grass balls (don't know how to call them) that grow in the grass can be carried to the wound, broken over it to heal (I know, it's really tough to realise this, my bad). The ending is triggering when the player goes at the hole, after the planet fully grows (10 mins in), but the endings aren't clear either.
Managed to do this with about 2 sleepless nights, but I also used lots of assets pre-owned or pre-made. The gravity and the planet itself took more than I thought it would, so polish, audio and the gameplay loop design got a hit.
