I enjoyed what I could play of this, but there were some problems on console. Palettes/graphics bugged out big time in the final 2-3 levels of World 3, and after beating the piranha boss (world 3) the game softlocks preventing you to play any further. Enjoyed what I could play though!
the first thing i'd like to say is that i think the hack goes from hard to very hard
and that this was the last hack i played on zsnes AND that you can not finish it on zsnes. the final battle breaks and you are stuck.
about that one overworld bug i already commentated.
some areas where youre supposed to trigger a vine block with a koopa (mainly the final castle, 3rd door) you can get stuck if you kill the koopa. there are only 1-2 koopas around and if you kill both you are stuck.
since im not able to open the hack via LM i cant look at the cyan level in the bonus world makes me sad.
the hack itself was really nice. i like the idea of playing "a bad guy" because you basically start in the last world, bowsers castle and lava levels and you go the opposite way to what is technically "marios 1. world" if he'd do the journey.
the autoscroller levels are a bit unforgiving. usually you have to stay at the right side of the screen and avoid obstacles right as they appear or you end up in a spot where an enemy will most likely hit you. its almost impossible to do the autoscrollers first try.
some levels with a foreground overdo it a bit. "leafy lakitus" is the best example for this. at the end theres so much foreground, its almost impossible to see. and either im too stupid or i just found no way that tells you where holes are.
music from donkey kong country, lufia 2 and other games that have well known tracks are included, the music is really nice.
i enjoyed playing the hack but it was a bit unfair at parts.
too many autoscrollers, potencial for softlocks, unfair levels.
it doesnt happen a lot but it does happen.
i feel like 3* fits this one pretty well.
i do recommend it if you look for something that reminds of kaizo, without being kaizo. it is a challenge, but it was enjoyable.
edit: it posted my comment 4 times no idea why. i deleted the 3 copies and hope its just one now.
