Of course !
For example, in classic platformer there's a mechanic where by pressing the jump button longer (or by simply holding it), you make a "bigger" jump, where you go farer.
In your game, that is not the case, the height and the distance of the jump is the same regardless of whether you hold the jump button or just press it.
In my playthrough, when doing long jumps, I kept holding the spacebar button during the jump. But as soon as I landed, because the jump button was still holding, the character jumped automatically again and for the tiny platforms, that made me fall sometimes ^^
Hope it was more clear!
