Optional Hard Mode is great. It's just E4, Gym Leaders and some trainers have more pokemon or pokemon levels are 5-10 levels higher than base game. Base game has a lot of awesome quality of life changes. HM moves are forgettable. Move Trainer in Cerulean will teach you any forgotten level up move for 5k. Move tutors will teach again for 5k. TM Vendor Machines at the top of Celadon Store means no more paying 80k for Ice Beam or 90k for Shadow Ball. Very Polished. Multiple play throughs, didn't find any bugs. Only Downside is no Sevii Islands because its a true Yellow Remake. As a Fire Red player that was disappointing. Virtually no postgame content that wasnt in original Yellow.
Great Game if you like Gen 1/Kanto/Yellow Version. Had a lot of fun with it.
