At the end of the day, it's his project and his business BUT I'd still argue that people would be far more forgiving if NEW scenes were added even if old ones aren't up to speed to the new ones' art quality.
I mean, for Pete's sake, the original sprite of David can still be triggered! There's no excuse reworking every single character sprite for him to still leave the old one tied to a trigger.
I'm OK with old assets to still be in the game (look at what dataminers have done with Bloodborne and other games with cut/unfinished content still left behind just inaccessible by normal means) but it undermines the effort of changing every sprite if you can still trigger the old one with no hacks/out of the box means.
