Almost every discussion I've had with non-devs on this forum is generally negative towards any balancing changes. You make the game harder. You nerf 1 thing people find is strong, and when people use something else, you nerf that too. Some playthroughs simple don't have the money for anything, the more demon generals you add the less the 100 days is realistic. You alter and nerf the stat gains from different materials, you increase the cost of blessed water when we have the least amount of money. It's almost impossible to meet certain time barriers without being in NG+, like say the festival reward bonus or even 80 day Belphegor.
I can't tell if this is all by design to deliberately make your game miserable thematically, but that doesn't work. If your game isn't fun, people stop playing. This isn't Elden Ring. We can't just out-skill everything. The numbers matter, there's randomness in the game. The player needs to be able to attain power realistically. The 'darkness' of the narrative does not work as torturous game balance.
I understand you need to keep to a schedule. You've been at this a long time now, and I respect that commitment greatly - but the balance matters too. Even for fresh files. If certain difficulties are intended to be ng+ challenges, restrict them to that as appropriate.
As it stands I'd probably bet your game on the hard difficulties as a pure character is quite literally impossible.
I don't really play anymore. I dip in and read the updates, particularly skimming the balancing section. I don't remember the last time I saw a positive adjustment.
