after a night of sleep i calmed myself, and i'm kind of embarrassed of my comment, by my point of view it looks like i'm blaming you, that wasn't my purpose at all, maybe you didn't saw it that way but i wouldn't feel fine until i make it clear, it was my fault for not paying attention while playing
i will do that, i finished the game with amy but didn't collect emeralds, when i tried to replay to collect the emeralds i made that mistake, and now i'm playing with her again, but will take a while, and actually found a funny bug in the previous run:
sorry for the low quality, i take the picture with my phone to send it to whatsapp, i was fighting eggman but i used the hammer to late so he hit me and while falling back, tails grabbed me, resulting in that, tails is froze there and i can move like it should while grabbed by tails, the bug fixed when i jump
and about the slowdown, is random now, when i opened the game today, it was almost without slowdown, since the moment i extract the new version i add the "/MIS1", sometimes work and other times don't, i feel it's my pc
