I told you level 8 was hard. XD
The boss of level 8 killed me a lot of times. Seriously-- BRING YOUR POTION. I toned it down ever so slightly, so it's not quite as bad as when I ran through it (I can elaborate more if needed), but it's still quite tough.
EDIT: Changes in pending update:
Level 1 - Darknuts gone, replaced with Stalfoses and Ropes.
Level 2 - Blue Goriyas replaced with Red in path to the raft, except the solo guy in the actual treasure room. Went from 7 to 3 Baby Dodongos in previous to treasure room.
Level 6 - Ladder room bumped up to 9 Darknuts.
Level 7 - whistle->secret room altered cosmetically, to make it more in line with similar secrets.
L2 Gibdo's animation fixed. Whoops!
@Nightmare : I'm not sure what you mean about the color and fire of the Fire Gleeok. Perhaps I have an offset wrong?
