Kudos for making such an addictive idle game!
Apart from making some of the tools available outside of the menu, can I also suggest moving tool menu screens into their own tabs? Similar to how tools+crops are separated from the land tab? I'm not sure why, but I always kept clicking on the land tab while going to pick up seeds to plant.
Also, how does the fertilizer work? I would expect it to be used on the ground either before or after watering it. However, that didn't seem to do anything.
