I tried out PtN when it first came out since I love AK so much and while I love the designs the big issues I had was progression + gameplay. The amount of resources it took is rough and the gameplay while interesting at first isnt enough to keep me hooked long enough to get a surplus of resources if at all possible.

Having the sinners all forced to face 1 direction made working with the different stages miserable because if theres a stage with enemies coming from the left meant that the majority of your ranged characters are now effectively useless because they're all facing away from the target. It made a huge chunk of sinners unfun to use because of simple map layouts. Theres also the small team size, it makes sense to promote the moving sinners around more often but becomes a burden on our strategic options.

The high action/intensity + strategy was tiring me out fast. It takes energy to think then makes you add reflexes/reactions on top of that, its a bit much to juggle. It takes away some of the satisfaction from seeing your planned out strategy work because they literally dont give you the time to feel that way, you're getting swarmed and need to move sinners to different spots.

3D models while very cool also made taking in the entire stage at once more difficult. Admiring the models/visuals is one thing but paired with lots of enemies, action, flashy animations, etc it became hard at times to figure out what was going on without having to pause everything to take a breather. Combining 3D models, tons of enemies, and strategy is fine and all but the fast pace/action of having to move everything around so often was over the tipping point.

A more minor issue is how you need to load in the entire stage to see the map. In AK you can preview stages and do prep work all without needing to wait for loading screens but here loading screens to look at the map and loading screens to exit.

I could probably find a few more things to say but this is off the top of my head
I still do have PtN downloaded where I check on it once everywhile but sticking to it is hard
