Not Finished

So I’m stuck. Sitting at 1/4 to level 3 and no movement at all. I feed the tree, I have done all the floors on the elevator. Several times, theres nothing left. There are no more active quests. My hitting tool is maxed. I can’t upgrade the gun. What gives? I love the game and was enjoying it. Now just nothing? Did you not finish the game. What am I missing?!?!?

This is a fun game but the NPC that is supposed to harvest the corn (guessing that’s his job) got stuck walking from where I rescued him to where I was supposed to take him.
