i have to beat him at gambling 3 times T-T ive already lost 6 times and i only have 200 gold left :( i guess i gotta go to the girl who gives me 1 gold every time i talk to her. i would recommend changing that part though because first off theres nothing that hints that he gives you the key as far as i know and second off if you get unlucky you run out of money and theres nothing you can do besides go to the 1 gold girl which gets annoying unless theres some other way to get money.
This is something I overlooked entirely. For some reason I assumed that the gambling game would be addicting and therefore cause someone to play it at least three times knowing they'd win money... but that was naive of me. The infinite coin girl was the last resort option so players weren't forced into resetting their run, but without me needing to implement a free mini game or mob killing area. I chose one coin each time so it wasn't worth using it to grind for the shop items... idk what I was thinking at the time. I will come up with something to improve this for future players!
