Rewind was the only way I was gonna beat that game lol The game cleaning up the sprite flicker and slowdown helps, but that game is a frustrating mess of just the worst hitboxes and incredibly poorly designed encounters. I got nostalgia for it, but it's a rough time for sure and it was neat to finally be able to beat it the first time.
I already posted in the challenge thread about what I've beaten, but I've mostly just played what are gonna be the "worst" games of the collection, like TMNT NES, Tournament Fighters NES, and TMNT 1 and 2 on the Gameboy. None that are particularly good, but I wanted to get to them first before I dove more into the Turtle in Time and Hyperstone Heist stuff. I did dabble in TMNT: The Arcade Game for NES, it's kinda rough, and TMNT 3 for Game Boy is neat, very Castlevania in its exploration, though it is suprisingly difficult I'm finding as some of the combat encounters can be abit rough. While still not up to the real good games, I am enjoying myself with this nice TMNT resurgence with the collection and Shredder's Revenge.
