This is a cool idea! One suggestion to make the mini-golf aspect better is to add more realistic physics to the ball. This might be harder to do in 2D than 3D, but the ball shouldn't be able to get in the hole at max speed without ricocheting off somewhere else. Would also be cool to see some hazards or maybe a stamina/cooldown system on the spinner, so the serious job application gets to you sooner.
Also, a minor bug is the "Back to Menu" button does not appear to be working.
