I had this half of the game made, the truth was I did not know how to program, make substances at that time but what I did not know was to improvise the levels, the level design was bad. but thanks to Game Maker I improvise the design of the levels now;) by the way I have to tell you that @WhiteFRIE is doing the fight of Sonic against egg. This fight will be more or less easy. Thanks for reading the article
