Your opinions on what is considered a good smbx episode/project?

[Eri7]

So after i set myself a goal about making the best smbx episode/project even tho many people don't believe that i could do that , i decided to ask you guys about your opinions on what would you consider a good smbx episode/project and why?
Here are my opinions:
I think that good smbx episodes are the ones that are consistent on what they want to portray , consistent on their quality through each level and each boss , consistent in the story and not making the story too complicated to understand , consistent on making everything related to the episode more and more exciting the more you play it.
Also episodes that do something unique that makes them stand out and manage to break my expectations on what is considered good and interesting.
The best kind of episodes are the ones that make you just go "WOAH" and inspire you to improve so one day you can make an amazing episode just like the one that inspired you.
Good smbx projects are the ones that break your expectations before you have even played them as a finished episodes.

Now your opinions.

I feel that good episodes would have a good, consistent flow; difficulty slowly increases, levels inside worlds fit together into one theme, an episode is centralised upon one idea, e.g. collect the stars. Episodes feel better when they consist of memorable levels, which brings me to my next point:
Levels. Good levels are those that have an interesting, unique gimmick idea. They should feel original to make me remember them more. Levels that aren't too difficult and can be beaten are usually better than kaizo levels; difficulty should alter throughout a level while keeping a good flow of progression.

Episodes are games that require SMBX to be played, as far as everything is concerned. So everything going into a good game goes into a good episode too. This means ideas with good execution, and as little padding as possible. Of course it takes time for characters to get from point A to point B, but in a good platformer, no level feels superfluous. It's a good ideas to plan out the structure of the episode first and then design it later, as that way ideas from early levels can be incorporated into later levels, making the entire experience more coherent. The two best 2d platformers I know are vastly different in terms of what they set out to do: Celeste and Donkey Kong Country Tropical Freeze. The former has 7 long levels that serve as chapters in the game's heavily focused and gripping story, the latter takes the concept of a mariolike platformer to the extreme with incredibly dynamic, rich and memorable environments that define each level. There's no winning strategy to making a platformer, so the best advice I can give is: Plan the story you want to tell and present it in the most polished way possible. A short but incredible episode and game will always be more memorable than a lengthy and decent one.

A "good episode" will definitely vary from player to player; nevertheless, what I think is a good SMBX episode is something that I can enjoy playing. An episode that actually doesn't make me bored, where each time you complete a level a new challenge is yet to face me or the difficulty rises and such, is what I think of when I hear "a good SMBX episode." Episodes that are too easy or too difficult aren't too fun for me. Level design is also a very important factor in making a good episode in my opinion; having good level design and mechanics can make an episode more fun. I also like episodes that aren't too confusing for the player and has a sense of direction on where it's going—plotwise, etc.
