I enjoyed it, until i bored myself by cheesing with left+down. After a while I noticed that you get more score if you exactly match the hole (it takes careful watching of the score to notice, which you don't have time for when enjoying the gameplay).
I suspect some audio-visual feedback would make that clearer, and also incentivise players to not cheese with staying the smallest size, but instead chase the high of the perfect match.
One other point i had is that it sometimes was hard to tell if I was lined up properly, so some kind of projection of where you're going (or lines on the ground as synesthesia34 suggested) would be nice.
This one has potential!
