Interesting idea, making Mario 1-1 sort of rogue-like-y like this! A mushroom and maybe a few sounds and the 1-1 song would be nice to have. I do like how you somehow made the art arguably a little better than the original game despite it having to be being twice as crunchy, it feels sort of cute. Death feels a little punishing though, having to restart from basic 1-1, because if you die on the revisions, it sort of just reverts to playing a worse controlled 1-1 we're already very familiar with over and over again.
