You play as Kulu, a cat who is summoned by the Mayor of Katz Village. As the hero, you are tasked to help him take over the world by collecting seven World Stones. The Mayor also a summoned Arika, a goddess who, for some reason, has amnesia, to help Kulu. Arika has the power to rotate Kulu's world, aiding him as he navigates through dozens of puzzles.
Tropes specific to a character should go into the characters sub-page.
Tropes specific to this game:
- All Just a Dream: The entire game world was dreamed up by Arika, who is implied to be a normal girl leading an unhappy life in the real world.
- Ash Face: Exaggerated with Kulu. His entire face is blackened to a crisp when he's exposed to the flames from the Flame Blocks.
- Block Puzzle: Some levels have non-hard blocks that Arika can move by turning the stage. They either serve as hazardous obstacles or steps for you to clear your goal.
- Doppelgänger: The World 8 puzzles involve controlling two Kulus. You lose health if either of them get hurt.
- Dream Apocalypse: What Mr. Soo plans to due to Kulu's world after he takes over the real Arika's body.
- Elemental Nation: Some of the worlds are aligned to a particular elemental, and this is reflected in their levels.
- Fanservice: Arika, between her looks and her...suggestive dialog with Kulu at times, almost single-handedly earns the game its Teen ESRB rating.
- Floating Continent: Katz Village is built on one.
- First Town: Katz Village (World 1) is the town where you start the level out with.
- Fission Mailed: If you touched the flames from the Flame Blocks at the exit, Kulu will still get burnt by the fire, but the "Level Clear" screen will play, indicating that you've win the level.
- Ice Palace: Icicle Palace (World 3) is a tall building within the cold world, where S. Nowman resides to do his research.
- Invisible Anatomy: If any, the katz species are able to hold their accessories despite not seemingly having any hands.
- Kill and Replace: Mr. Soo plans to use the World Stones to take control of the real Arika and erase her along with the rest of her dream world.
- Lethal Lava Land: Flame Mountain (World 6) takes place at the volcano.
- Nintendo Hard: Particularly the Hard World puzzles that are unlocked after finishing the game, which mix and match world-specific gimmicks from the normal game.
- Palmtree Panic: Block Sea Island (World 5) takes place at the beach, having the ocean to swim in and a Light Block that floats on water.
- Playing with Fire: The Flame Blocks, which spew out fire on one direction. The distance of the flames are indicated on the blocks.
- Plot Coupon: Kulu and Arika collect 7 World Stones to help Mayor with his world domination. The World Stones turn out to be a metaphor for the real Arika's heart.
- Punny Name: The game's title is a mashup of "block" and "kuru", the latter being how the protagonist's name is rendered in Japanese and similar to the Japanese onomatopoeia for rotation. (guruguru) Unfortunately, this gets mangled in translation.
- Shock and Awe: Upon collision, Shock Blocks discharge an electrical shock around 1 area.
- Slippy-Slidey Ice World: Icicle Palace has Ice Objects, where the terrain is so slippery, Kulu slides along the platform.
- Spikes of Doom: Cave Rock and Medusa Forest has spikes that causes you to loose a turn on contact.
- Smooch of Victory: Kulu earns one from Arika in the ending.
- Taken for Granite: Activating the Gorgon Block turns Kulu into Stone. This does not cause him to loose a turn; on the contrary, it protects him from other hazards such as spikes.
- Under the Sea: Played with with the Block Sea Island, where its initial puzzle is partially submerged in water for Kulu to dive in. In level 4-7, the stage is completely submerged instead.
- Video Game Settings: Each world takes place in different environments, having their own sets of obstacles appropriate to them.
