Finally, after 1 year and a half of work, I completed my first ROM-Hack, named Super Marix World.
It's a kind of kaizo hack and not so many people have played it, so I want to upload it here because I need some feedback.
It has a total of 27 exits (included the 4 Switch Palaces and the special world) and 4 boss fights.
I hope you enjoy it and that you will give me some feedback!

During the tests I found a problem cause by the Retry System when you enter level 23 (High Plains). When you are shooted from the cannon when you enter the level, after loosing a life and retry, you are not able to get the Yoshi again, so you have to exit and enter again in the level. I'm working on it to fix this little problem! If you find any other problem let me know!
