ORA ORA ORA

back again. if you die to the spikes, you get stuck on them. also idk if its just in knuckles' first stage but if you get to 0 lives, the whole game restarts, idk if that was intentional

i don't like how hard the knuckles boss fight or maybe that's just my skill issue

What's the problem with the archivement for the Eggman and Metal Sonic solo ending? I've done it more than once and it still hasn't unlocked. Great game BTW, I just feel like this bug should be fixed so to have the 100% of the game Trophies.

I really love this game and I can't wait for the duo endings and the best ending, anyway I hope we'll play the duo endings.
