Considering the configuration of many of the holes, stroke power is waaaay off, and it needs an arc indicator at minimum. Change that and I'd give this another try.

Enjoy this calming and simple golf game that you may find addicting and difficult. Try to get your ball in the hole in as little strokes as possible. Challenge yourself to get the lowest score you can.
It's fairly good; although could be better if there were other kinds of obstacles – e.g. different terrain types, interactive (moving) elements. Sometimes I thought the ball is inconsistent – it sometimes stopped on what I'd consider a hill, and sometimes (the very end of the last level) it kept rolling on a slightly tilted surface despite being really slow.
I'd also write the total number of holes somewhere; I almost quit because the game got too repetitive in the end. Which is fine since there are only nine levels; but if you added more eventually, you'd definitely have to introduce new elements to the gameplay later on.
