Adventures of Lolo (Japan)/Floor 4

Password: PKPH
Part 1 (Don Medusa):
 * 1) Position Lolo to either end of the starting "corridor". When Don Medusa is on the other side, grab one Heart and take cover under the next one. Repeat, and grab a second Heart next to the previous one. Now position Lolo under the middle-lower Heart, half-tile on it. When Don Medusa in on the "empty" side, step up and rush to the side to grab the last three Hearts in the lowest row. You should have two magic shots.
 * 2) Position Lolo to one side of the central Emerald, and step half-tile down. When Don Medusa is on the other side, quickly grab the two Hearts on your side. Repeat for the other side.
 * 3) Position Lolo north of one of the Hearts aligned with Don Medusa. When Don Medusa "bounces" against it, dash and follow it, grab the middle Heart, and run back. You should have two magic shots.
 * 4) Position Lolo above either one of the central Snakeys. Quick now: shoot it once, push it between Don Medusa and one Heart, grab it, run back, shoot away the egg, and get cover behind the Emerald.
 * 5) Push down the Emerald (between Don Medusa and the other Heart) and use it to trap the moving enemy between two rocks, on either side.

Part 2 (two Medusae):
 * 1) Push the upper Emerald to the right, and grab the nearby Heart. Shoot the upper-right Snakey and push it up. Grab the nearby Heart for two magic shots.
 * 2) Almost the same, on the left side: shoot one Snakey, push it left, grab the nearby Heart. Shoot the upper-left Snakey, push it up, grab the last Heart.
 * 3) Shoot Gol, push it up, walk around it and grab the jewel from the box. Now leave the room.

Before any move, study this room carefully: which Heart shall be the last? The arrows and the Hammer power leave little doubt: the one against the east wall.
 * 1) Grab the five Hearts to Lolo's left: he obtains four magic shots and the Hammer power.
 * 2) Shoot the central Skull twice and grab the central Heart.
 * 3) Cross the one-way arrows and get to the upper-right corner. Quick now: shoot the Skull just once, push it to the left and grab all the Hearts on the way. Only when the egg starts cracking, then shoot it away. Grab the lower-left Heart for two magic shots, and rush back before the Skull reappears.
 * 4) Get to the Skull near the last Heart. Shoot it twice, go down and break a rock above the Jewel box, grab the last Heart and rush to get the jewel before the Skulls get Lolo! You can then leave the room.

The alternance of sand and normal terrain make the positioning of eggs very tricky in this stage.
 * 1) Start by grabbing the nearest Heart and therefore two magic shots. Leave the next Heart untouched.
 * 2) Position Lolo on the one-way arrow next to the Snakey. Quick and precise now: shoot Snakey once, push it left, up, then right against Medusa. If the egg breaks before you do, or if it is pushed too far, you have to restart the room.
 * 3) Grab the Heart just below Lolo. Backtrack and push the Emerald up and left, between Medusa and the Heart above her. Grab that Heart, then push the left Emerald down one tile.
 * 4) Position Lolo to the right of the topmost Snakey. Quick now: shoot Snakey once, push it left, then down across the sand, then right under Medusa, the up against her. If the egg breaks before you do, or if it is pushed too far, you have to restart the room.
 * 5) Collect all the remaining Hearts, grab the jewel from the box, then leave the room.

 * 1) Go up and grab two Hearts, thus obtaining two magic shots and the Arrow power.
 * 2) Shoot once the Snakey to Lolo's right (just above a Heart), and push the egg all the way to the right. Grab the four Hearts in the center, thus obtaining two more magic shots.
 * 3) Go towards the Heart in the lower-right corner, passing north from the Snakey you just pushed. Target the Snakey that is to the upper-left of the Heart: shoot it twice and grab the Heart.
 * 4) Go all the way up, until the door. Reach the last Heart by walking on the top two rows only.
 * 5) From the last Heart location, walk two tiles right, then down as much as Lolo can. Use the Arrow power on the one-way arrow, then shoot the Snakey and push the egg down. Take a tour to the right in order to reach the jewel box.
 * 6) You can still get trapped by the arrows: just walk straight up, one tile right, then up again, and exit from the door.

You should use the Leepers to make a safe corridor between the Medusas.
 * 1) First of all, touch a Leeper so that it blocks the eyesight of the lower-left Medusa, and at the same time makes the lower-left passage accessible to Lolo alone. Symmetrically, do the same on the right side, but leave those two Hearts untouched.
 * 2) Grab the Heart just below the Skull to get two magic shots (and, obviously, the two Hearts on the way).
 * 3) Make the aforementioned corridor by touching more Leepers (this may take many long attempts), and leave the last one awake.
 * 4) Shoot the last Leeper once, and push the egg just above the left row of Medusas. Wait next to the egg until it breaks open, so that Leeper falls asleep on that tile.
 * 5) Grab the Hearts at the top. Shoot Skull once, and push it up and right near Gol.
 * 6) Grab the last two Hearts, in the lower-right corner, then proceed to the jewel box and to the staircase.
