Super Orb Bros. is a difficulty-oriented ROM hack of Super Mario Bros. 3 that takes the orbs you get from defeating Boom Booms and makes a game revolving around them. While in the vein of ROM hacks like Air, this one is more like a puzzle game where various tricks have to be utilized in a specific manner or else you won't be able to progress. Thankfully, you have an infinite number of lives, but in turn, you get a death counter.

Mizumaririn decides to skip most of the intended gameplay routes through the use of glitches and obtain all 18 orbs for Old Man Grimm (don't ask what he needs them for!) in order to pet the dog in record time.

This movie has an Atlas Map encode that shows the game overlaid on a zoomed out map.
