The thing is: The mini game is slow paced and too tedious. It would be better and more enjoyable to speed it up and overhaul it all together in a DDR style mini game. When you reach chapter 8, you already played it over 70 times and sorting 100 bits in one session feels like a chore.
Decreasing the upgrade prices doesn't help as the debts are still too high. In chapter 7 you have to pay 50K, but only get 7K per day because of the cryptoheist. That means you can only get 56K per week, getting 50cals costs 5K, getting an upgrade 5 to 12K. Chapter 8 has the exact same problem. You should either increase the rewards, decrease the debts or add a new thing to hack.
I see you improve from game to game, but the balancing and made it punishing to pay for anything but the debt. Otherwise it would be an amazing game. I don't care about the story, but even I see that you care about it and write it competently.
