This is a vanilla hack where you play as a Monty Mole.
Almost no custom things were used.
-You can now carry items and punch nets.
-Removed time limit in "End of the hack".
-Removed the message boxes in "Generic Grassland" and "Morton's Castle".
-Changed the "presents" logo.
-Monty now turns red when collecting a fire flower.
I just finished this today, and I'm impressed! The player character is really well done, with some good use of sprites, but I feel as if his jumping animation should be a little more involved, it seems too similar to the walking one. The level design here is fantastic! The second half of the stage with the dolphins was super satisfying to snipe Koopas with a Fire Flower in, and the autoscroller in Morton's Castle, was actually really fun! I did notice some slowdown in "Bullets and Chucks", but it was manageable. Overall, a really well designed hack with a really cute idea.
Overall, this hack isn't fun at all.
Sometimes, there are some blind jumps here and there. Also, in some levels (like 'Bullets And Chucks'), there is some serious slowdown, though maybe that's just me playing on a real SD2SNES cartridge on a real SNES (or rather RetroDuo).
In 'Bullets And Chucks', there's this annoying part where you have to hit a hidden block with a purple coin under it over a falling platform over raft on lava that is sloping down to a bottomless pit. If you get on the platform too much to the left of it, it will fall when you are about to hit the hidden block and when (if) you land on the platform, it will be too low for you to jump high enough to go over the hidden block. And even when you are high enough, it's just the bare minimum. Earlier, in that same level the football itself was used as an obstacle, but it still relied on an RNG like in the original game, making it literally random how high it'll bounce, which is a problem when it's used to block progress. Also, in that same level, you are barely given enough time to really think and strategise through that level, which you'd definitely need to do in a level like this.
In general, with the way levels are, the L and R buttons are a godsend, allowing you to look left and right. However, the way they were implemented in the original Super Mario World, apparently, you have to let go of all other buttons for them to work, which can break the pace a little.
I'm glad this is not a demo. It wasn't really fun at all, but at least it doesn't waste too much time.
This is definitely a hack. Levels are competently designed but not all that interesting.
My biggest issues are that Monty's hitbox seems to be a little taller than its graphics (you can see that Monty doesn't quite connect with hitting a block from below), and that there's no obvious visual difference between regular and "big" Monty.
