I noticed 2 small bugs in Coral City and one probably unclosed tag for if you follow a wisp.
first, if you go to the Amphitheater and examine the building, you are kicked to the Split Island.
second, the second time you get to 3 arches, there is an unclosed <span> tag.
I also found about 4 or 5 minor typos. I'm not sure how best to present them.
I wouldn't have found these bugs if I weren't so interested in the game!
The wisp graphics are attached.
