Start your file and go left to the jump powerup, then grab the green square on the same screen and go left to the portal (1 SQ)
Teleport to the jungle and take the upper path to the grey dungeon
(optional) Grab the health upgrade at the beginning of the grey dungeon
Keep heading right up the ladder and continue past the save station (save is optional)
Keep heading right and jump through the screen with plasma back into the grey dungeon
Continue to the right until you reach the first ladder, go in the first entrance on the right
Continue to the right until you reach the eyeball boss
Boss Fight: Stay on the ledge and mash the attack button until the eyeball opens and raises, then drop
Continue mashing throughout the fight
The eyeball will shoot differently each time it resurfaces from the plasma, and there is a 5 pattern cycle that occurs, to dodge the bullets, do the following:
- Do not jump
- Jump when the eye is at the middle of the plasma http://gyazo.com/ee2743c03e6136e84dcc9c2046277089
- Jump right when you see the eye appear at the bottom of the screen
- Do not jump
- Jump when the eye is at the middle of the plasma (same place as 2)
Repeat this process while mashing attack to defeat the boss
Fall down and get the goggles and (optional) the health upgrade then use the portal
Use the goggles to reveal a staircase to your left, then go inside for another Square (2 SQ)
Exit the room and go to the left one screen and drop down the small ladder and go right
Drop to the very bottom right of this ladder and go right for another Square (3 SQ)
Go back up the ladder to the right, maneuver through the maze screen and drop into the overworld
Climb the mountain until you reach the top, then use the goggles to reveal a passage containing a Square (4 SQ)
Exit the passage and go right towards the castle. On the screen with the entrance to the castle, use the goggles to reveal a staircase to the final Square (5 SQ)
Done (Shoutouts to ZorlaxSeven for discovering the 5 cycles on the eyeball boss)
