The Hardest SMBX Level You've Played

[Mosaic]

What's the Hardest SMBX level that you've played? Kaizo does count as well.
My hardest level? i'm not sure yet. But you can post down below.

[RSupertheGreat]

I'm stuck in Rosalina's level/stage, I might lost when I just accidentally go to the bottomless pit.

[Cidro]

Hardest level I played? The winning CC1 level, Stormhead Sanctuary ( if that's what it's called ) if you're serious about it. I keep dying over and over again.

Sanctuary fortress 2 from CC11. You don't know what is a real annnoying and frustrating experience until you play that level.

The hardest that I actually succeeded finishing without any cheats or outside powerups was maybe Funny Tanks

and from the ones that were just too hard, there's indeed those Tier 3 levels in ToBX and also reghrhre's "this level contains touhou music" (winning CC3)

[PixelPest]

Probably Sturg's winning MaKLx3 level. That was brutal. And I thought mine was hard

Thank you for reminding me. I need to re-record that fun level. It has been a year or two since I last played it.

[HeroLinik]

I have a few.

AI Boss from CC2 (Rinka spam, unpredictable attacks, doesn't give you enough time to grab the projectiles)
Sanctuary Fortress from CC11 (do I even need to explain this one? It's so easy to get lost)
Tree of Echoes from CC7 (pretty cramped)

AI boss from CC2 is one of the easiest levels I have ever played honestly. It is not unpredictable. It is too predictable honestly.

[Mivixion]

Played? It's one I'm still tweaking.

Beaten? That's MECH's icy mix extended
