Thank you for trying and sorry it left you disappointed!
It is good feedback, and you are right, the game is barebone at this stage, and there is still a lot I need to add, balance and tweak...
Sorry the tutorial broke, it would have helped with at least some things, like it guides you through researching the Farming technology (so that you actually can farm rice after completing it), and explains the cultivation at least a little. I will look into why it broke.
The easier difficulty allows to play without having to worry so much about the decay, but I guess there is a better way to go about it. I will remove the difficulty setting and instead have two game modes: one with and the other without decay (buildings upkeep will stay). I will also make it so that the mode can be changed without having to start the game from beginning. Hopefully, it will fix the "maintenance guy" feeling...
Thank you so much for the feedback! Reading and seeing stuff like this is exactly why I made the game public even though it is not exactly ready - these concepts look logical in my head, but I do need actual players to tell me about the confusing parts!
