use the arrow keys or W, A, S, D. Also for fun if you press the dino it will change colour and if you keep on pressing it, It will look so cool! Oh yeah and does pebbles are just a design. If you want to reset everything press the green flag.
You can use arrow keys if you are better than using W, A, S, D. I'm better at using W, A, S, D so ill use that. Also when you change the colour of this dino it is sick cool. Also, I think this dino is sketched. Anyways make sure to star and heart my projects and type something cool, funny, or nice in the comments.
