The first time I played this was the fanmade Vita port, which has abysmal loading times whenever you time travel. I just didn't engage with that mechanic at all and judging by a second playthrough, I was right to do so because time-travelling kinda sucks! It's an interesting idea for sure but not on these stages with this level design. And if you don't use it, most of the levels are too short and overall unmemorable. Bosses suck too, but the callback to Labyrinth Zone's boss in this game's water world was cute at least. This is someone's favorite Sonic, just not mine.
