Around 28 minutes to beat using built in Save States on this Nintendo Store version. I consider Save States legit for this completion since they are built into the game. I have beaten this game legit on multiple other platforms as well. I missed the world 8 warp and got too far. Since I restarted that part isnt shown here.
I used save states at the beginning of each stage on the final world only. I didnt use them mid-stage which would have sped things up.
