I love the little twist to the mini-golf! The gameplay and physics felt so smooth, and it was challenging to score a hole while hindering the opponent connected to you. Honestly, the AI opponent you programmed whooped me to oblivion.
It fits well with the theme as there is a connection between the two players/golf balls. One critique is to replace the arrow with a line as it's hard to accurately hit the ball the way I want to. I would think I am aiming right as the arrow is aligned but then my ball would miss.
Conclusion: A job well done! Hope you make a bigger game about it.
