Okay, I've found a more major problem that does affect gameplay in a specific spot: In Cotton Clouds 4, shortly after the fifth star coin, there are two Pitching Chucks with a small slope in between them. Something's wrong with that particular slope, because attempting to walk on it causes you to fall through it and die. I think there's an incorrect tile within the middle of that slope that causes this issue.
Also, the world 7 boss fight has issues in my opinion. The instant the boss flips upside down, you can't land on him, or you'll get hurt, even if you're spin jumping, and the upside-down flip can happen instantly without warning. You also get hurt if you land on him while he's in his spinning shell right after landing a successful stomp, again, even if you're spin jumping.
EDIT: Just finished the hack, and found one more "major" issue. When you beat the final boss and rescue Peach, she gives the message for when you first find Yoshi in the vanilla game. Whoopsie!
I just started co-op playing through this hack with someone, but already found a couple of minor issues:
While playing 2 player, during Luigi's turn, the points shown at the top of the screen are actually still Mario's. I noticed this while watching my partner play and noticing that their score wasn't changing, and then when it was my turn, it turned out it was my score. So, Luigi's score seems to never be shown at all.
Also, after getting the "hurry up" warning for dropping below 100 seconds, the music tempo remained fast upon returning to the map, and persisted into later levels, until a boss was defeated, at which point the tempo finally returned to normal. EDIT: Turns out Start+Selecting out of a cleared level also resets the tempo.
Like I said, though, these are minor and don't actually interfere with gameplay, but I figured they were worth mentioning anyway.
I'm in the middle of the hack and i really enjoy it!! Great level and great music. Some slowdown like in many others hack but not too disturbing for me. I give you 5 stars. Thank you and keep the good work !
- The vertical free-scroll camera made it harder to focus because Mario's surroundings moved around so much. It also made a lot of jumps blind that otherwise would not be.
- There was a lot of lag. It's unfortunate that it wasn't fixed after it was mentioned during bothprevious moderations of this hack.
- This softlock was not fixed. I fixed it by adding a ceiling.
- The hitbox for these crushers is several pixels wider than the spikes, which is particularly bad because the crusher spikes in vanilla Super Mario World don't hurt you.
- The fact that this hurts you but these do not is visually confusing.
First: Great Hack!, im just finishing world 1 so i may edit this comment.
Second: At Grassland 2, if you carry a buzzy beetle shell to the final pipe, you can see you didn't put the same Sp4 for both levels.
Third: Song Name At Grassland 4? ;)
Edit: im in world 2 now, and in the yellow yoshi level, there's a part with some slowdown, at the part with the 2 pokies, and the turnblocks
