A Big Change To Mario's Formula

Reviewed By: peacefighter on 23 Aug 2021

This hack makes Mario huge and makes you play in a new way. You now have obstacles in your way. The level looks pretty much the same as before but now you are too big so you will have to jump or duck in order to continue. I like that I am playing Mario but now I have to look at the levels and their design completely different. This is a good addition to the classic game. I do recommend this game.
