Luigi controlled differently which is fine but the obstacles didn't have anything to build on with those different controls. For some reason the wall jump didn't work in the ghost house section of the castle level either. Just confused on some of the obstacle placements.
I really like the graphics and concept of this hack, but in practice it's nothing special. There's nothing wrong with making the player character more agile or stronger than normal, but the level design has to make up for that. Unfortunately, the level design is pretty weak and it seems like obstacles are added for the sake of adding obstacles rather than thinking about creative situations that take advantage of Luigi's attributes. Though this may seem minor, the grammar and sometimes spelling in the text boxes is often awkward and makes the hack look less professional.
Wall jump breaks this hack, as you can skip large level sequences unintentionally. On the other hand, this hack has quite a few bullshit areas, such as the forced hit after a midway point and the spike layout in the castle before the boss. All in all, frustrating experience.
This hack also overuses the P-switch to clear areas, particularly in the second level.
Luigi's handling makes him seem like he's played up to be a god - he can run on water, his jumps are extremely high even for being Luigi, and all those wall jumps. It's a very weird hack, and none of these attributes are utilized well.
