How do I improve the control of my player?

I made a mobile puzzle game where the player ocntrol a chameleon.

My problem is the control is very slow and unresponsive. It's really annoying and break most of the fun.

The point is, I juste don't get what make them slow in the code and how I can improve it?

Here is the code, the move are made by pressing a sprite arrow (use a button) or by swip.

Here is a link to the gam if you want to try it

What is all this code about arrive and depart? Anyway it doesn't seem slow it's just unresponsive. Use 'touch' instead of 'tap' to be more instant. And make the collision box of the arrows big enough for the player to comfortably touch.

Arrive and depart is about the swipe. As it's a mobile game, someone suggest me to add this possibility of movement.

I will try the touch thanks
