Coding school entry test game

Hey guys.This game is part of an online application for a coding school.Its got absolutely no instructions but im supposed to ‘add some controls to the functions to give the arrow head direction to get to the star’ but i cant move the arrowhead

Please help if you can

We can’t interact with the image so it’d be better if we had a link to interact with or the code you are supposed to adjust.

O don’t think theres a way i can share coz its an online test and its strictly 2 hours.I was just wondering if any of our good coders in here have come across it
