Thanks and glad to see that you had some fun with it. I may change the waterfalls at spawn to see how they look because wading in water can be annoying. The main reason that I didn't really have any underwater areas in the map is because iI think it is annoying for the player. I will probably add it to some optional exploration part though. Thanks for that idea. The diamonds are provided generally early in the map so the player can save up for the Diamond block and then use any other diamonds in the map for personal use.
Thanks for the feedback, it means a lot. I'll probably try adding some more exploration bonuses. I already have some, but very few.
