Perhaps see what you can do here?
I already read this link. Maybe I'll have to contact the support of itch.io 'cause it's the only thing I can do now. Thanks for the help anyway.
I have contacted itch.io support and they provided me the download link for the game. I apologize for any eventual inconvenience and for the late reply (they took the entire weekend to answer my e-mail). Also, thanks for the help and your attention. As a big fan of Megaman and other old-school platformers, I'll certainly enjoy playing your game. Thanks again ;)
