Amazing graphics, honestly. Problem is the rest of the experience is a little lacking. Here are a few improvements I can think of:
-Music, even a simple tune or chord progression to set the mood, search up an online DAW and just mess around until you have something you like.
-Make the gravity a bit stronger, you jump way too high in the air and fall way too slow
-Sometimes I can't input a hole because there is an object too close to it, it's a little annoying that my hole placing abilities are so limited, so I'd try and improve that.
Otherwise, a great entry
