Tip: Entering a door or pipe, activating a P-Switch or grabbing a star, completing the level, hitting a message block, and dying will cause issues on the title screen, such as causing musical glitches, or trapping the player in an endlessly-looping level.
Mario and windows demo with 10 levels level 1 and 2 are short built
This hack doesn't meet our quality standards. Levels have no structure and feel the same, with the changing aesthetic being the only thing that sets each level apart. The windows aesthetic itself is the main issue. It's too hard to tell what anything even is.
The screenshots suggest the levels were changed but they still suffer from all the issues in the previous post. If you don't make an effort to give your levels any kind of structure at all, your hack is not going to be good enough for the hacks section.
