Hope you all enjoy the video! I really liked how the transitions turned out so let me know if I should keep making transitions like that!

If the volcano theme was in the game, the gimmick for that should have asteroids or black smoke that would be so cool

The dark Ghost House are not that bad, when they're designed well.
Yeah, not easy to find, but I don't agree with the "just instantly skip without even trying"

The dark themes can work well for hiding secrets and creating ambient atmosphere. Just be sure to balance it with well-placed light sources so it's not too annoying for the player.

Nighttime ghost house is actually great, you just haven't played any good levels using it.

I wish there was a beach and volcano theme.

Edit: I wish Mountain and Tower were in the game too.

I actually kinda think the ghost house night theme can be used to good effect. An example was an old level from near the beginning of the game that worked to recreate FNAF, and it worked quite well.

No but seriously, night time ghost house can be really fun to play with, since you can't see anything, it's the perfect theme for maze and puzzle level.

20:40 this is the most perfect song you could’ve chosen

Imagine if you could mix night theme effects....
shudders in upsidedown dark

Although I can understand why people have a distaste for the night variants of the underground, underwater, and ghost house themes, I honestly like them a lot. I have used each of them multiple times, and they can lead to some cool course ideas.
Now night time underground is just "everything upside down", which obviously isn't much of a change. Of course, the complaint from most is the change to the controls, not the unoriginality, to which I say "seriously?" I mean, sure, you're not used to it, but its not that difficult to get the hang of folks.
Night time underwater and ghost house are probably my favorite night theme just for the gimmick alone. It can be used in so many ways. It works especially well in horror-type levels for obvious reasons, but a good use I found was platforming (just listen). Since P-switches and POW blocks produce light, you can use them to light up the platforms you want the player to jump to, and you can even hide secrets in the dark. You could also place the items on a track and have the player need to follow the item so they can see ahead. Underwater courses can make for good cheep-cheep mazes (as seen in the story mode), and can be used in a sunken shipwreck stage for an atmospheric touch. Now sure, not being able to see what's in front of you makes no sense in a platformer, but with how easy work-arounds can be made for it, you really shouldn't be hating the theme for that reason alone (at least imo).
TL;DR: Night time underground, underwater, and ghost house themes are my favorite themes, and can be used in some creative ways, but people just keep avoiding them because of the flaws that they have.

“There is a Ludwig”

Me: what

3:09 best gimmick ever.

I’ve actually seen some fun low light levels, using coins with fireworks to boost light for a moment gives Mario a level that encourages coin collection, especially underwater!

7:45 also, if you have a star active, the rotten mushroom will run away from the player

3:09 is the DuckTales moon theme.

I wish the night theme had the backgrounds of the day themes, but darker and with a night sky

23:02 why is this kinda fire

4:58 favorite part of the video😂
