Is Nightmare difficulty fun?

My only playthrough was on Nightmare difficulty, and I had a lot of fun.

I can't say for sure, but I'd assume you'd have to beat all missions on Nightmare from a New Game, since there are some missions (1st loops) that can't be replayed from a completed save file.

I played on Hard and then replayed on Nightmare. It mostly felt the same as hard except for a few places where it was noticably nightmarer lol. The most annoying place for me personally was in Sleepless zone RE where you should deal with slitterheads using only civilians. Damn they were instakilling everyone right at the start and then one time they decided not to instakill thats how I got lucky to clear it. Also Lisa boss fight was hard. Other then that it felt comfortable.
Also I never checked after clearing on Hard about whether full game should be cleared on Nightmare for achievemen because wanted to replay full game anyway. But someone said that it should, I saw a topic about it.

For the achievement I believe you do have to start and complete a full run without changing the difficulty. If you change the difficulty at any point during the run, those achievements become voided and unachievable.

I had lots of fun with nightmare, but I already liked the combat a lot the first time around on normal :P

I think there were only 2 fights where I was genuinely no longer having fun: The first was in one of the Sleepless Zone loops, the second was Lisa. I died to that more than the entire rest of the run... Plus an honorable mention to that one shrine in the meat locker

And yeah, you have to beat the entire game, from selecting New Game on the menu, on nightmare difficulty. I assume because being able to have all abilities unlocked already would make it easier?

Once you realize you're basically god by doing infinite switch and ping pong abilities spam the game become stupidly boring.

You can break all difficulties with this loop and sadly it just negate all gameplay, humans/powers/passives/dodge/counters/slow mo stuff mechanics everything is useless.

Can I ask where you're getting this impression? According to your achievements you haven't beaten the game or even cleared the hardest boss fight on any difficulty yet, so I doubt you know how hard Nightmare actually is unless you started with it. Did you play in offline mode or on another platform or something?

IDK which difficulty you're on but there were a couple patches that made counters easier on difficulties besides Nightmare (IDK how much easier). So if you feel like it's easy and you're not already playing on Nightmare, I'd recommend bumping the difficulty since it apparently does more than just change damage values.

No, and so is hard. To be honest after almost finishing it I can't give this game more than 5/10. Theres just so much wrong with it. Bokeh will have to do a much better job with their next game.
