I wanted to know if it is possible to relpicate the gameplay of super mario world, like power ups that change the sprites of the character, the “spin jump” that makes the enemies have a different death animation (the little explotion), having a different jump height depending on how fast are you running, picking and throwing enemies and stuff like that.
i’m kind of a beginner so i don’t know what’s possible and what’s not.
I don’t know that game, but what you wrote can be done with GDevelop. 
Fortunately you could do all of that with GDevelop.
There’s lots of examples included with Gdevelop so it’s worth having a close look at those. You’ll find many great tutorials on Youtube and I learned a bunch of stuff from there fast. For example, check Wishforge latest tutorial about a platform shooter. You can pick up ideas from this and modify it to suit your needs.
i’ll be watching those tutorials.
Thank you so much!
