In Project Heartbeat mere milliseconds can mean the difference between a record breaking run or an absolute failure.

As a result, we are in an everlasting quest to lower latency and increase input consistency.
As part of the Project Heartbeat Phoenix update the game is getting many upgrades and changes. With the game's new game engine, we've replaced the input system and developed cutting-edge rhythm game technology so you will never unfairly miss a note again.

The game's logic is now completely dettached from the framerate, through the new advanced tickless system developed specifically for Project Heartbeat Phoenix.

In previous versions of Project Heartbeat, your input used to only get checked once at the start of each frame. Any button presses you did after that got snapped to the start of the next frame. With the tight and fast gameplay of Project Heartbeat, this could mean the difference between getting a FINE rating and failing a perfect run.

With the new subtick system this no longer matters, the game now knows when you've pressed every single note and is able to precisely evaluate it. Effectively acting as if you were running an infinite frame rate.
