Heartbeat Tempo Trainer
The Finale scene in No Means Nothing pins the player under a heartbeat that accelerates from a 2-second interval down to 0.4 seconds. The slow phase tightens 2s to 1.5s over the first 6 seconds; the fast phase then ramps 1.5s to 0.4s across the next 20 seconds. This trainer reproduces every value verbatim from the in-game heartbeat config asset and lets you rehearse the full 26-second arc in three modes.
Verified tempo breakdown
Heartbeat Config.assetThe in-game heartbeat config asset sets six tempo fields. The heartbeat starts at a 2-second interval between beats. Over the first 6 seconds it accelerates to 1.5 seconds - this is the slow phase. From 6 seconds to 26 seconds it accelerates again, this time from 1.5 seconds down to 0.4 seconds - the fast phase. By the end of the arc the player is hearing 2.5 beats per second, which is the tension the Finale scene is built around.
Tempo curve
Phase mappingThe interval shrinks smoothly inside each phase, not in steps. The slow phase eases the heartbeat from calm to tense; the fast phase cranks it from tense to frantic. The trainer computes the exact interval for each moment using the same formula the in-game controller uses.
Interactive trainer
Tempo curvePick a mode, hit Start, and tap Space (or click the Tap button) on every beat. The trainer measures the gap between your tap and the nearest beat in milliseconds. Taps within 30ms count as Perfect, within 60ms as Great, within 100ms as In-Pocket. Your best average deviation per mode is saved to this browser only.
The first beat fires about half a second after you press Start. Tap along with every beat. The trainer stops at 26 seconds and writes your average deviation for this mode to your browser.
Where the heartbeat shows up
Scene mappingThe heartbeat drives the Finale scenes. It is most audible during the bath LockDoor task and the Labyrinth walk. The bath task gives the player 10 seconds inside the slow phase and the opening of the fast phase; the Labyrinth walk keeps the heartbeat running across the full 26-second arc.
Common questions
Config-backedHow fast does the heartbeat go in No Means Nothing?
The in-game heartbeat config asset sets an initial interval of 2 seconds between beats, a slow-phase final interval of 1.5 seconds reached over 6 seconds, and a fast-phase final interval of 0.4 seconds reached over 20 seconds. The full Finale heartbeat arc is 26 seconds long, and by the end the heartbeat is hitting 2.5 beats per second.
Why does the heartbeat speed up during the Finale?
The Finale scenes - the bath LockDoor task and the Labyrinth walk - are tension sequences. The heartbeat controller accelerates the interval across two phases: a slow 6-second ramp from 2s to 1.5s, then a fast 20-second ramp from 1.5s down to 0.4s. The player is meant to feel the walls closing in as the interval shrinks.
How is the trainer scoring my taps?
Every beat is scheduled ahead of time. When you tap, the trainer finds the nearest scheduled beat and measures the gap in milliseconds. Taps within 30ms count as Perfect, within 60ms as Great, within 100ms as In-Pocket, and anything wider as a Miss. Your average deviation across all taps in a run is the headline score.
Which mode should I start with?
Start with Audio follow if you have not practiced rhythm games before - you only have to listen. Move to Visual pulse once you can hold 80ms average on audio. Finish with the Finale simulation, which pairs audio and visual cues and is the closest to what the in-game scene throws at you.
Does the trainer send my records anywhere?
No. Everything stays in your browser under the localStorage key "heartbeat_best". No backend, no telemetry. Your best average deviation per mode and your total tap count persist across visits on the same device.
