How to get 'Thomas was alone' type of Jump Mechanics with Phaser.ARCADE

[PixelProgrammer]

Hi there,

  I'm creating a platformer game that is similar in art style and theme to Thomas Was Alone. I'm currently using the Phaser.ARCADE Physics system for my game cause it suits the theme well enough. 

However, I want to implement a jump mechanic that is similar that is similar to Thomas Was Alone. https://www.youtube.com/watch?v=aAfgZrt_93k

As of right now, my jump mechanics is a simple: 

if ((this.player.cursor.up.isDown) && this.player.body.onFloor()) {
            this.player.body.velocity.y = -300;
        }

What do I do to make it feel less 'space-like' and more 'springy'??

Increase both world gravity and body velocity when jumping. Physics will happen along the same curve, but faster.
