It was going to be non-Kaizo, and then a Kaizo thing, and then I revisited the first idea because I didn't want to make myself a liar, and to reach a wider demographic.
This was an interesting gimmick I thought of that completely changes everything about how this game is played. Mario can't walk left or right but he can still jump.
To compensate for the Nintendo hard difficulty as well as helping to not get too repetitive, the levels will be fairly short, about like SMB3, with no midway points. In addition, since it's fairly easy to get stuck, you can reset using L and R, and "dying" results in being reset back to the beginning, making lives meaningless.
Other than that, and using some hex edits, it's pretty much vanilla.
Rise over Run
The first level.
Mario comes to terms with his disability.
Rise over Run pt 2
Couldn't think of a better name. It was originally part of the first stage but I split it because I couldn't have Mario reset at a point other than the beginning. So it's sort of a harder reiteration of stage 1.
The number of levels will depend on how many ideas I can come up with, but I don't think this hack will be that long.

How am I so creative? I think taking walks might have something to do with it.
Every single level I will ever make in SMM2 will be easier than Ultra Necrozma.
