Mario&Luigi is fanmade Mario game !!!Tricks: !!Jump-on detection: This game seems to use the common jump-on detection algorithm in Mario games: If you are moving downward while hitting some enemy, you jump on it (and don't die unless it is piranha plant or spike top). !!Piranha plants: Piranha plants don't hurt mario while they are popping up from pipe (while going down they do hurt him). !!Left+Right: If you press left+right, Mario instantly changes direction. !!Cornerboosting: If you hit block suitably from below, you go bit inside it and get ejected. This saves 2 frames a pop if performed correctly. !!Picking up bonuses inside block: If you hit block that's ejecting bonus with sufficient speed, you go bit inside block and hit the bonus, picking it up.
