Just finished Intermission on Hard mode and here are some scrambled thoughts. I finished Remake on my Pro so getting to playing through Intermission at 60fps on PS5 was just what the doctor ordered for the frenzied fighting. I really liked the Fort Condor mini games, simple yet fun. Yuffie is amazing, both as a character and her English voice actress as well as her battle system. Square could really have screwed up the Remake but so far it's been a blast. Yes there are a bit over the top Nomura stuff with the Whispers but on the whole it extremely solid experience and the DLC is no exception. Hard mode was VERY hard for me at first, I totally forgot to level up my weapons, so I didn't have a lot of stats or materia slots equipped or leveled on the new run, I only figured it out half way through the next run LOL.
The boss battles are a treat but they were as I said really hard for me at first, trying to figure out their attack patterns and replaying quite a few time until I managed to take them down in a way I wanted (usually I want to finish with a Limit break or similar strong attack at the end of a stagger). Also the system and all the combinations are a bit difficult for me to pick up on in one run, it was the same with Remake, I had to play it a second time on Hard to really get a good grasp on the system and combinations/strategies down but once you do, it's super fun.
However there is one thing that made me rage a few times and it's the auto targeting mechanic and lock on. There were a few fight with many drones or turrets all over the place and the boss attacking you at the same time and it was nearly impossible to not make mistakes with what I was targeting, I had to resort to X to slow time down and retarget there and in some cases there is obvious targeting priorities by the game, you try to taget the boss (not in X mode) but the character simply auto attacks a turret instead, and some times when you want to taget the drones they attack the boss.
Also it's a bit hard to get a good over view of the action at times, it's likely they designed the parts of the boss battles to be overwhelming on purpose by not being able to see everything at once and some times enemies teleport and you lose the lock on and you have to manually move the camera to see what's going on, but then at other times when you are locked on and you try yo look around to see what the hell is happening you instead change the lock on to the wrong taget, argh! I know you can change the setting but they aren't as good in general. That said, I still loved this side episode and I'm cautiously optimistic that they won't screw up episode 2.
Some final notes, I would have loved to be able to chose a bit wider camera angle and some times if you get pushed up against a wall the camera won't pass through it and the close up action becomes a complete mess.
