FAQ:

Q: Can't you just flip the arrow trigger instead of rotating it?
A: Nope, rotating it would just make it so it turns the gravity upside down. My problem is that it always turns it right side up. Arrow triggers always affect the player's gravity.

Q: Can't you just use a collision clock/collision ticker to trigger stuff every frame?
A: Yes. That's how I'd do it in 2.1... I just like this method more because it's easier to set up and less laggy. You can also set up some more advanced conditions by changing the item's value that its comparing

Imagine a rated classic mode level that halfway through just turns into a platformer level.

This isn't platformer mode! I think we need a "I Made "Real" Platformer Mode in Geometry Dash" video NOW!

The brainrot has consumed me, I practically knew there was gonna be a congregation jumpscare as soon as you dropped in a black void....

1:34 DAMN IT 😭

"platformer" wave is from now on CONFIRMED

1:36 DON'T LOOK PLEASE NO

well, its akshually its really simple: since normal mode is just platformer mode with a wall constantly pushing you forward, we just have to remove that wall from normal mode to make platformer mode in normal mode

"Jaaam, what did you do? Robtop's crying again"

this is kinda(?) unrelated to this video but i want to mention that back in 2019-2020 there was a 2.2 gdps based on the 2017 (or somewhere around there) version of subzero and there was someone who had recreated platformer mode in classic mode using p1 and p2 inputs. im really glad people managed to recreate "fake" platformer in actual 2.2 :')

He's insane...
And jam

That was fun to watch

This video should have been titled: “I Made Platformer Mode in Classic Mode!”
