Game

I downloaded this game and it won’t even load.

Was fun, now won’t load.

Played the old version and capped out. Downloaded the 1.5 update, now can’t play at all. Won’t load past 60%.

Stuck attempting to upgrade

The game is awesome but I can’t seem to go further no more tasks available unable to increase levels of the purifier or Axe please fix the issue

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?!?!?

Help!

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.
