Yeahhhhh it's just not for me. I think I'm not really a 3D platformer fan in general, so you can take this with a grain of salt if you want. But Penny's Big Breakaway was janky as hell, had some super broken sections (the boat boss fight), and the general platforming I just couldn't get into.

It feels really weird. I'm sure if you're a speedrunner and you are really good at using the yo-yo, it feels great. But I'm not, and it didn't. It's got the momentum-based platforming of a 2D Sonic game which feels good for about 2 seconds before I start falling into the void. When going fast, I would fall off so many edges or go flying into the abyss. But if I go slowly, that's boringggg and it feels like I'm playing the game wrong. Overall the platforming just never felt satisfying to me even after my seven hours of playtime.

Also I don't really like the artstyle or cutscenes or story or characters. Which is kind of a shame because I LOVE Sonic Mania and have played it so many times.
