Oh nice! Yeah I play-tested it and it took me about that time too, I mainly made it to just learn the engine etc.
Thanks a lot for the suggestion!
Awesome! Another idea, you could make it so if the balance is negative, it gains compound interest every few seconds like a real-life loan so people feel pressure to quickly earn back their debts.
Nice game! Maybe make it so you can't swap more than you have (since atm balances just go into negatives) but other than that it's fun!
