Hey Phyrocast, thank you so much for checking the game out & for giving such wonderful feedback - i totally understand your point - yesterday was the first time for me to beat the game - so i know its possible tho! I couldnt play test while creating the game - it was too little time.
But the best ways is: search trashcans - buy sellers pmit - sell items - go to restroom - then blackmarket - finish the day by sleeping in the hotel (the only wayy to reset the dark vendor and the trashcans) - sell a lot of items, mostly BlackMarket Coins
