Press the flag. It will take a while to load, but after the sky is loaded it should be okay. Trees won't spawn depending on how much dirt there is. Sometimes a sun will spawn during night or a moon during day.
I'm proud of this because I did this with the only help being someone telling me that I should try to use sprite only variables more often as that prevents lag. This project only took a day to make so obviously it's badly made and is buggy.
