Thank you for your feedback, it helps a lot! There will be more than one way to obtain iron in the full game. That is just the slow and basic way before you upgrade to get faster ways of obtaining lots of iron quickly. I do plan on fixing a lot of the RNG that's in the game, like rain and the bird drops, for the full release. It will also have WAY more content than the demo. The demo was about 5-10% of what the full game will offer, so I hope you look forward to it!
