I've been playing this and got right up to the Final Boss, died and then realized I hadn't saved in like an hour and a half after I died (my first death in the entire game)
...so I think I'm done, I don't feel like redoing the entire last spirit dungeon + the various bosses that lead up to the final boss. In a way I kinda wish the old men still prompted a save, because I just straight up forget to save often and they'd ensure at least a trickle of saves at key moments (and at places where the game was balanced to save anyway)
The graphics are alright, although coming off the nice 2D artwork of the other Wonder Boy games on the Switch, this one leaves a lot to be desired. I watched a few minutes of the original and noticed Pepelogoo actually had an animation for going through doors (it pops in with a magical sparkle), while in the remake it just... clips through the wall or gets stuck or whatever and it's not as smooth. Asha's default pose also looks pretty stiff when rendered in 3D, almost t-pose-esque
It's a really fun game, though, and maybe some other time I'll try running through the original game. It doesn't seem like there's much different between them, and I always find Genesis music and graphics to be charming. And with the old man prompting me to save, maybe I'll save more than once every 2 hours lol
