I would say it’s reasonably difficult. I haven’t beaten the 100 levels yet, I’ve only gotten up to 50, but it may be that the developer expects you to unlock more permanent unlocks before you can fully beat the game
But there are times when a boss gives you quite the bullet storm so it may be difficult if you aren’t coordinated
No more bugs than RDR2 at this point. Characters will still do silly animations once in a while but that’s pretty much unavoidable in big games, I feel.
Definitely play it. It was one of my top games of 2023 when I played it. I didn’t want it to end once I’d beaten it
