Imagine having a full beautiful game like Celeste with these mechanics, like, literally Celeste 2? That would be great, a sequel with a new main character (which I love the design btw) I like to think both the Celeste Classic games were uploaded to see the community's opinion on it and maybe, just maybe, make a full game.
I think the new mechanic is really good, but it's not nearly as satisfying as the dash mechanic from Celeste, it's too strict and doesn't let you choose your path of flight, you can only go in a straight line, left or right and jump mid-air, which doesn't let the player be creative with where they want to go.
