Simple hints for all puzzles:
#2: The bulb's function is to power the four adjacent tiles. In other words, two adjacent bulbs can create a "perpetual motion" effect! Use two bulbs in the first column to repeatedly light up the ladder, making the second column cycle multiple times while using the flashlight to activate the horizontal ladder above, then move similarly sideways. Also, watch out for some strange flying objects (
#3: The functions of the blocks are fairly straightforward. Keep two bulbs adjacent and use the clover's rotation effect to make them traverse the entire space (like tank treads!). After the second task begins, a thunderstorm will trigger every 30 turns, destroying all unprotected areas (i.e., those without an umbrella above them). So try to move the umbrellas upward quickly!
#4: The two bulbs and two clovers at the start form a single unit. Try to move them together as much as possible. Maneuver around from above or below to eliminate all enemies.
old #5(scrapped): The puzzle itself is simple. Pay attention to the story hints! The correct password is do - mi - so - #do
#5: A bit complicated... First, try to move all umbrellas you find at the start upward to protect other tiles from thunderstorms. There are many enemies on the right, so it's best to collect all the wings on the left before tackling the right side. Some finer details also require attention.
