Playtesting finished. This review is for demo 4, I should test demo 5 too.
This hack is great and has an interesting storyline, I've played World 1 and World 2 so far, and I haven't found any issue as for level design, traditional design with some gimmicks twists which I like.
Most of the issues found are related to grammar.
Zomer Hotel:
1. Change are for is as it is only a museum

2. It would be better to say; It's women's toilet. Also, this text boss fun but... Luigi isn't a pervert, is he?

3.Correct word here would be enjoy (not enjoyed) and wish (not wished)

Dialogue with Andonuts (#1 Andonuts Lab):
Correct expression: Are you thinking about stealing it from me?
Also it should be Delightful Children gave instead of give.

Dialogue with Luna (Marincess Labyrinth):
You missed an m (remember notremenber)

One minor issue I found in Zomer Hotel:
There is part with a swimming pool which looks like it has no characters to talk to, but checking in LM after completing World 1 shows there are two characters. Minor, but if you fix that, it would be good. I lost that screenshot sorry for the inconvenience.
One question about Lumiere Pirate Ship, there is a door over red switch blocks which seems unaccesible, am I wrong? Is there a way to get there?
Apart from that, I haven't found any issue in World 2, so great work!
(This review is unfinished so the post will be updated. Ninja Boy, thanks for you tip provided)
World 3 has been completed. Gimmicks make the levels feel new and different from the rest. The fact of the camera not moving back to the left in the sky section of Celadon Forest 1 makes the level have a SMB1 feeling, which is good. Also, I enjoyed Callisto Circus levels due to the unique gimmicks used there ()
#3 Celadon Funhouse is a great level, enemies that cannot pass the pink blocks make the level a good challenge. However, I found a minor issue there:
Blocks are acting as vines in this part of the level.

Also as a question:
Finished World 4. Arid Heights Levels contained fast paced action which made them a challenge. Good job! Cerise Volcano levels introduce, which I think putting them make the level great. Small issues found:
Not sure but I think that vine in Arid Heights 2 is not necessary:

Grammar issues:
If is not necessary there while Luigi and Mega Man D are talking to Buff in Arid Heights 3:

I would change I can for Can I and an ? next to you...:

Instead of personnel it would be personal:

The shouldn't be there, being just: Mario's twin Brother?:

In #4 Bowser's Castle, the is used wrong as in the previous screenshot. The correct would be: Is Bowser using the Supercrown?
. Also change told for tell:

Change having for had:

World 5 finished. Again, new ideas and good level design. Nipticks and issues:
In the bonus room from Lustful Beehive, getting the coins can be difficult when you have a bee chasing Luigi:

Waiting for the spikes going up while another bee chases Luigi can be tough:

Unexpected spike, maybe an indicator?:

In Starry Sky Canyon 1, if you don't know about the movement of Chucks, you may have trouble, though it's not hard if you know that:

Grammar issue in text boss from Starry Sky Canyon 2, change are for is:

Also, it's not hard to find the secret exit, but an indicator for some people would be good.
Finally you can skip the end of the lift travel when having a Feather Cape:

And now for some grammar mistakes in #5 Mineral Temple, when talking to Shad/Ninja Dusk:
1.Correct ones would be: You were brainwashed too? and Those delightful dorks...

2.It's time to teach you good manners

3. I would recommend deleting way and just changing painful for painfully:

4. Not a grammar mistake, but when:

5.How dissapointing is the correct one:

6.Again renember, correct one remember

7.How did you escape...:

Minor issues, but still a great world!
World 6 done, it was a great world with some awesome ideas (like in Blue Springimmicks and Rouxls Kaard Level when )
Most of the issues (which are small are related to grammar):
1. In Winter Panorama the same text from Mega Man D repeats twice. Also the correct one would be: Don't touchin and for a couple of seconds not in:


2. In of Rouxls Kaard you should add to before hit:

You could put here: What did you do to him? or What have you done to him?:

Gave, notgive and be before able:

You missed an a, it's INITIALIZING:

3. In Clockwork Fortress, too and the wouldn't be necessary:

Not a grammar issue, but I think it could be a good idea to introduce how work, or maybe I don't remember?
4. In Blue Springimmicks, England Knight's tip contains a very minor issue. The correct one is I not i:

5. Again not a grammar issue but in Winter Meadows, that Blowing Cloud made Luigi going through the floor, not so minor issue but not big either:

6. In #6 Winter Hideout, Merla should say Did you enjoyed:

Put Let me see or Let's see:

An extra minor issue I found, you can access Amethyst Mansion without playing Basilisk Forest:

Apart from that, this is one of the best worlds in the hack. Great job!
Factory World finished. Fast-paced platforming with new ideas for those platforms. Great work! Seems that the OW is WIP and the Red Switch Palace is the one from original SMW, just with a repeated battle (I guess Red Switch and Sword Junkyard are still being made).
Now let's see the issues found in the levels:
In Burning Gimmicks 1:
1. I think this can be unfair, deleting one bully would make the level more enjoyable:

2. Those block are trespassable, I can't get the secret exit:

In Burning Gimmicks 2, there is slowdown in that part of the level:

In Sword Junkyard, there is a grammar mistake, it is Why don't... instead of Whydidn't...:

World 7 has not a specific theme, levels have different ambiences and gimmicks. I found the levels good and fresh. Don't turn back... was a great level. Some issues found.
In Amethyst Mansion, if you aren't careful enough, some unfair situations can happen (Boochimera is an original and great idea):




Grammar issue in Beat on Brambles, is aren't, notcan't:

Careful there, don't throw enemies to those platforms, the can be defeated:

Finally, the characters which didn't appear they did it finally, just another grammar issue:
Correct one would be He's really making me sick.

That's all for demo 4! 4/5. (Ninja Boy, I finished this playesting)

cannon which launches Mario in Callito Circus 1 and moving springboard based on DKC3 in Callisto Circus 2

Blocks are acting as vines in this part of the level.

Also as a question:
Cake Secret Area is supposed to be a powerup collecting level? Is it a placeholder?
Finished World 4. Arid Heights Levels contained fast paced action which made them a challenge. Good job! Cerise Volcano levels introduce
orange cement blocks which can hurt Luigi when standing too much time over them
Not sure but I think that vine in Arid Heights 2 is not necessary:

Ninja Dusk becomes invisible, item from the box doesn't escape

5.How dissapointing is the correct one:

6.Again renember, correct one remember

7.How did you escape...:

Minor issues, but still a great world!
World 6 done, it was a great world with some awesome ideas (like
blue platforms which make Luigi jump
you have to solve puzzles
Most of the issues (which are small are related to grammar):
1. In Winter Panorama the same text from Mega Man D repeats twice. Also the correct one would be: Don't touch


2. In
the first puzzle

You could put here: What did you do to him? or What have you done to him?:

Gave, not

You missed an a, it's INITIALIZING:

3. In Clockwork Fortress, too and the wouldn't be necessary:

Not a grammar issue, but I think it could be a good idea to introduce how
