Thank you for taking the time to play and give critical feedback! I really appreciate it. It helps me know how to improve the game.
I agree with you completely. I'd designed different mechanics for each ore to make them unique. I like the idea of different colors for the trees, too! I'm conflicted on days passing automatically. It's definitely annoying to press the button, but I wanted to make sure the player was aware of what was happening. I could potentially have a sound cue play and a brief wait before the day passes, so you know to expect it without having to hit a button.
Also, I planned to add modifiers based on the day that would have made the gameplay more dynamic. So one day, you'd get more minerals from calcium nodes or their effect on trees would be greater, etc.
