The complexity comes in because some of the holes get extremely tricky. And holes never repeat.
I was really confused after hole 18... there was no menu, no stats screen, no selection options... it just went to hole 19. Then 20. Now I'm on hole 503 and I thought it was time to write some thoughts on the game.
Honestly, this isn't ever going to be a game that you monotask. That is to say, this is a perfect game to play while doing something else like listening to a podcast or watching TV. It's great as a second activity when you're doing something that doesn't take up all your mental RAM.
It seems like this desert goes on forever. So, it's a game I'll keep picking away at over time. It's pleasantly simple.
Oh! And one time I saw a CACTUS! EXCITING!
