Before I could get this game to run, I had to copy the Introverd_Data folder into the main folder next to the .exe (it said it couldn't run because it expected that folder there).
The idea is funny, but I think the balance needs to be adjusted. I can't get enough coins to buy the upgrades needed to survive before I die. I didn't really appreciate the offensive upgrade options, though I understand that fits the quirky theme of the game. But since it's unbalanced there's no way to earn enough money to buy them anyway.
It's a creative idea and a good effort, just unfortunately difficult to play because of some probably simple adjustments. Keep trying!
