Alright, I have to say... this hack is pretty bad. It would probably be removed had you uploaded it to the "Hacks" section. So, here is every single error I could find in this hack. I took a long time getting all of these, so I hope you actually fix these errors.
Here we go:
Three errors here:
1. You shouldn't die on the title screen of a hack.
2. It's a 1-1 remake. You shouldn't remake levels from an official game, as this just makes the hack look bad.
3. The "ack30" letters have a black background.
1. The "item" in the status bar makes the item box cutoff.
2. Why are there random red letters and numbers?
3. You should capitalize "welcome". Also, why does it say "CUSTOM MUSIC COMING REALLY SOON!!" when there is already custom music in the hack?
Unedited overworld?
1. Bad status bar palette.
2. The ground's palette is iffy too. It's too bright.
Capitalize "mario", "i", "my", "peach", and every instance of "bowser".
1. Yoshi is really cutoff. Why?
2. Two moons? That's really not necessary. And they both have different colors for some reason.
Mario's climbing pose is cutoff, and doesn't fit with the normal small Mario.
A clearer look at cutoff Yoshi.
Why is this turnblock solid?
Why does this block act like a POW-block? How am I supposed to know that?
1. That slope is cutoff.
2. What's the point of the coins?
1. There is some dirt around that land-pole thing.
2. Why do I bounce up and down on this block?
1. Mario's hat is cutoff here.
2. The pipe palette is weird.
That palette is very bright, and clashes with the pipes.
Why is this "used" block the same style as SMW, but not SMB, which the room is themed upon?
When I break these brick blocks, it makes the pipe cutoff.
Why can't I jump through these bridges?
1. All of these corners in the water are cutoff.
2. Remove the line on that corner tile.
Why does this piranha plant have a red stem? It's ugly and might cause VRAM errors. Use the
piranha plant fix patch in the patch section.
Those cement blocks are cutoff to the water.
1. Why are these throw-blocks here?
2. This section is really flat.
That pole looks very weird, and is cutoff when it connects to the cement block.
I have
a lot more, but please fix these first.
You can find the hack in his My Files section.
