Description: This is my very first hack. Been working on and off on it for 2 years. I didn't want to submit it until I thought I was fresh out of things to do completely.
The Story takes place after Super Mario Galaxy. There is a new original use I thought up for the Bonus Star counter. Some music I ported or made on my own and some from others. I recommend you play with both bros in this game but you can go solo with Mario if you like.
If you find any bugs or glitches PM me about it and I'll get to work on it.
Reasons
It is well-made overall, but there are a tad too many issues for me to accept this.

Missing "corner" tiles for tree tops.

Some perspective issues (especially in the lower right corner) and some missing corner tiles.

What's up with the message box's bounce sprite?

What if you aren't fast enough and the P-switch runs out before you're able to go on? A way to reset would be great.

This was a quite common issue throughout the hack: Cutoffness caused by pipes. Especially the sort of cutoffness in the second screenshot has to be fixed. Not only this particular instance, of course - look out for all other spots where this issue appears.

Glitched overworld events everywhere. Forgetting to uninstall the title screen recording ASM hack or editing wrong palettes can be the cause.

Please apply the Fade Fix patch.

The palettes don't look so good, and the whole submap looks pretty boring in general.

Although it's not absolutely necessary, it would be great if you made custom edge tiles for the pipes.

Some flying question / used blocks disappear. Use a different sprite memory setting or apply the "No more sprite tile limits" patch.

Something's wrong with the background assembly (below the pyramid, to be exact).

It took me long to figure out I had to go thorugh the quicksand to go on... It would be nice of you gave some kind of hint.

A floating Bullet Bill shooter?

The ground tiles have dirt behind them when they aren't supposed to.

Not that much of a big deal, but the top part of the platform being partially green looks odd.

Also a common issue: Yoshi coins placed on a sub-screen boundary, allowing you to get infinite lives. Just move them up or down one tile, and there you go.

This is why you should block the part below the pipe with cement block or something.

How did I die here? I can't remember if this was the fast-running part, but if it was, you should look into it, or remove that running sprite if it doesn't work.

In many places, you had passable pipes or ground. It's not a removal reason, I just think it can confuse the player a lot. Just wanted to point that out - maybe you can find a replacement for them.
(Oh, and you should give all pipe tiles layer priority, or you can still see Mario.)

Hardly visible BG garbage, but still garbage. See if you can find a fix for it.

A message box...

...turns into a used block?

Some perspective issues.

Aren't there corner tiles with water behind them?

The top part of the ground seems a little cutoff... might just be me though.

This, however, IS cutoffness. ;aybe you should just use different tiles that are only 16x16.

Another floating shooter.

Cutoff pillars.

More diagonal pipe fail.

The slopes seem cut-off too.

I got stuck in that pipe...

Missing corner tiles.

Wrong FG Initial Position.

Floating munchers? Lucikly they were the only ones in the hack.

Cutoff wall.

Misplaced piranha plant.
I was unable to beat that level... I can only hope that it's one of the last ones, and that there aren't any other errors after that.
As I said, this was a rather nice hack, and it would have been a great one if id had not been for these flaws. When fixing them, be sure to look out for other places that have the same issues too!
