I'm not a level maker by anyway shape or form, but i tried.
This is the entrance to a water temple. The idea of the blue squares in the deep water is that the player has to jump from one to the next to get to the entrance and if they miss they get warped to the beginning.
Kinda got lazy towards the end and didn't want to do a lot of detail on the ground, never really been a fan of it anyway.
I added a few tiles so i could try something with the cliffs. Didn't work the way i wanted but oh well.
Enjoy
