Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
A skeleton advances one tile every two beats, two tiles away.
- T2
Turn 2 · The player chooses
Hold a beat to let it step into range.
- T3
Turn 3 · The feedback
Next beat you strike and it falls; coin multiplier +1.
- T4
Turn 4 · The next decision
A bat on the left moves randomly; get ready to turn.
How it plays
Actions must align with the music; on-beat inputs earn bonuses while misses lose them or cost you. Enemies move to the beat too, making patterns predictable, so tactics and rhythm are tested together.
What the player weighs
- Wait a beat for the ideal move or rush
- Focus on rhythm or on the enemies
02Start small

03One mechanic, different implementations

Crypt of the NecroDancer
Every move and attack in the dungeon must be on the beat, enemies follow fixed beat patterns, and off-beat moves break your multiplier.

Metal: Hellsinger
In this FPS, shooting, reloading and dashing on the beat deal more damage and build Fury; off-beat shots still work but pay less.
The difference worth noticing
NecroDancer makes the beat a mandatory turn; Metal: Hellsinger makes it an optional high-reward bonus.
Case notes are Yoroll editorial summaries; rules may change between versions.
04What could you combine?
Enemies show their intent one beat before attacking, and players decide within the next beat whether to dodge, block or strike first.
