Help me make Mario like game

It’s essentially conceptual, I ran into too many problems tring to construct a working version of Neofax
but u at least started it? and u want to make it a side scroller with a tile base, ok does this game jump cause that immediately means i can’t tell u how to do it.
I’m thinking that i should make a basic tile based side scroller like mario, and just hand people the source for it, then they can sort of see what to do and at least they’ll have a start. but i’ll have to do it probably when my exams are finished, and thats about a month away.
PS sorry for stealing jomans mario tute
