Great game!
But I have some issues:
Then the shift is over and you need to press shift to close shop, if you was in the "shop with upgrades", you can buy upgrades, close "shop with upgrades" and continue making money without closing shop. If you close shop in this state, the new day screen is appearing, but mouse is not.
Also, costs to upgrades in "shop with upgrades" are not saving, and you getting new upgrades for cost of 1st level upgrades and can repeat it and get reacheast person in this world.
