NIN8HALOS'S PROFILE

This level was almost perfect. I am jealous. Feels a bit too long for an early level though. Also the springboards only bend on the left side, so when you put them sticking out to the right and the player jumps on them it doesn't look good.
Your selection of music and graphics give me hope for this project.

*sobs quietly*

Which is the correct title? Your zip folder and your level folder have different titles.
Blowfish revert to spiny eggs upon death. Was it necessary to resprite the mushrooms? It doesn't have a purpose. Change it back. I like the feel of the level, but there are so many problems with it. Others have already addressed this, so I won't say anymore until those things are fixed.
I do like riding the shiny block though. That was nice.

First of all, the checkpoint should be halfway through the level, not a couple screens from the end. Make the level longer or move the checkpoint back. The angles of the terrain are very awkward in some places. Those three mushroom platforms under the flipblocks look really cluttered and are unnecessary. You could get away with one. The goalposts at the end look out of place. Raise the star up too. It looks awkward that close to the ground. Gameplay is fine, but the aesthetics aren't so great in a few areas. SMB3 brick blocks are also out of place in SMW-style level. You could resprite them or something if you want to keep them there.

The level starts out bland and flavorless. Add some more background objects. Good level design overall. It's too easy to skip most of it though, since there are cloud paths overhead with many delicious coins. The hoppin' Chuck was a nice touch, but he's hovering off the pipe a bit for some reason. I also like what you did with the rising and falling pipes. You should help me out with SMWX, since I've pretty much exhausted my creativity. But that's for another time.
I like the underground section. The fish were completely unnecessary, but it's little extra things like that that make a level taste good.
Also you should totally change the color scheme to look like a glazed donut. That would be sweet.

That's what you should have called it anyway, cuz it would be awesome.
First complaint: This is way too hard for World 1. It's at least a 3. At least.
Somehow the flying bloopers don't make sense to me. Not in this stage. It would be better with moving blocks, crush traps, stuff like that. I love the custom graphics, by the way. I'd suggest moving this level up a few worlds and elaborating on it. The conveyor belt part was cool, but otherwise empty. Also make sure Mario can easily jump out of all the water pits. I almost got stuck in one of them right behind a fire-hammer Bro.
One last thing: that section where you climb the platforms to get to the Toad and his rocket is boring. I'd suggest mixing it up a lot. This level has great potential.

No one is going to go through that much effort to get the third Dragon Coin. The giant block near that pipe also has only a mushroom. Remember, it needs to have a flower/leaf.
The pipes are all grainy. Your image editing was done wrong.
The SMB3 black background at the end is barely even there. I'd say it doesn't count. Do it right.
Good level overall though.

This level is 90% coins. No one is going to spend half an hour hitting all those blocks over and over and over again.
And what's with the end of the level? It just keeps going past the star, over a cliff, and then onward into oblivion. And there's nothing there!

The checkpoint should be SMW styled. You also need to fix the ending because it doesn't conform to the rules. It also might be better in World 3. Maybe. It's an okay level though. I don't like or dislike it.

If you continue from the checkpoint, you get stuck forever.
Change the checkpoint and ending. It's almost like you designed these levels for a different game and them stuck them in here.
