Fun concept; to improve on this, I think that you could take into consideration how your game plays. The game works well on mobile but for PC users- having the arrow keys be the player movement instead of WASD was a missed opportunity here. Having Space key as jump requires your left hand to be used for space and right used for arrows- but to change the values of your jumping sliders you have to remove your right hand from the ARROWS to move the MOUSE. This makes the gameplay less fun, and a bit annoying to manage. It breaks the game feel.
It works well for mobile, because of how little the users hand has to move to make those adjustments quickly and return to the game. For PC, it adds more steps and longer wait times between actions.
