Rhythmove Dungeon

Rhythmove Dungeon (リズムーブ) is the 6th Endless Game in Rhythm Heaven, unlocked with 27 Medals.

Gameplay
In this game, the player controls a white head with four yellow arrows pointing in each direction. The goal is to get through the grid-based dungeon while avoiding a monster, ultimately reaching a tile with a door, which opens to reveal a staircase which clears the stage.

Each quarter beat, a different direction lights up (up, down, right, left in that order), and tapping on the corresponding beat moves the player one tile in that direction. The game is scored on which stage the player reaches. The player starts with three lives. Stages 10, 20, 30 and 40 have a heart near the end of the path, collecting which gives the player an extra life, for a total of five.

At the start of each stage, the player can safely stay on the starting tile, with a white circle moving with the optimal timing through the maze. As soon as the player taps to start (and moves in the proper direction), the monster spawns two tiles afterwards.

During Practice, the player simply has to navigate three halls, with a secondary character giving an example nearby. Stage 1 ~ 10 feature simple layouts, with the player running away from a slow monster.

Stage 11 introduces swing rhythm, altering the timing. The song alternates the two rhythms on roughly each stage after this. Stage 21 onwards repeat the layouts from the first ten stages, but with bottomless pits instead of walls, requiring the player to be extra careful with their timing. Stage 31 onwards uses a smaller grid, making the maze longer, and speeding up the monster. Clearing Stage 40 loops back to Stage 1, with increased speed.

Reaching Stage 11, 21 and 31 unlocks a simple select screen, allowing the player to continue from those stages.

Trivia

 * As the stage counter goes back to 1 after each loop, it is impossible to have a higher score than 40. As the high score counter increases simply by reaching the stage, the player technically does not actually need to clear Stage 40 to get the highest score.
