What do you think?

ORA ORA ORA

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

weird bug but when i logged in and completed the eggman & metal solo route it didnt give me the achivment for it

"Helper" bro i did nothing :joy: :v:

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
