[Spoilers] I don't know if I can go on

[Craig]

After dozens of attempts, I finally got my 3 keys, got to the next place and got the heart. I took my so long, but I finally did it.

But that's only 1 of them and after looking at maps people have put up, I haven't even discovered all of the islands I need to complete. After finally succeeding after hours of trying only to learn I have to do it again, and under much more difficult conditions, I just don't know if I can bring myself to keep trying.

Is it really worth me to keep trying?
