Appealing colors!!
The graphics should improve, so I tried to improve them, by selecting white with checker textures, and a little faded backgrounds with fogs.
Some people complained about the colors looking unappealing, so here you go, I hope it is better.
Checkpoints!!
If you wanted to go somewhere in the main courses but you don't want to start from the beginning, then I added checkpoints to start from hole 7 or 13 (out of 18 holes).
