Very original idea. In the middle of my play-through I though "Oh, this is like a pool game and a golf game mixed!" and then I re-read the name and felt really dumb hahahaha.
Quite a smart idea that fits the theme!
Since you had some time left, some simple background music would be a nice and simple way of elevating the game. There is a lot of free music in the community! Some way to feel 'challenged' is also something I notice makes the players more invested (some countdown timer, or some score, or max movements, etc).
Also, games with HTML5 versions get much more visibility on most Jams. And I believe Gamemaker has some html5 export functionality built-in (that's what you used for the game, right?).
Good job :)
