Want to fine-tune your controls in Hyper Light Breaker? With its fast-paced action, precise control is key. Unfortunately, currently there's no in-game sensitivity setting. This is a known issue the developers, Heart Machine, are actively addressing, with plans for a future update. They've announced this on Bluesky, promising a fix alongside performance and accessibility improvements.
While waiting for the official update is recommended, there are workarounds:

Workarounds for Adjusting Sensitivity
Mouse and Keyboard: The simplest solution is adjusting your mouse DPI. Increase it either through your mouse's hardware settings or using software. Keep in mind this affects your entire system's mouse sensitivity.
Controller (DS4): If using a DualShock 4 controller, you can modify joystick sensitivity within DS4 software. These changes will generally apply to Hyper Light Breaker. Alternatively, configure your right joystick to emulate a mouse, then adjust the sensitivity as described above.
Steam Forum Method (Advanced): For more technically inclined players, a Steam forum post (link provided below) outlines a method involving direct file modification. This requires comfort with navigating Windows system files. We strongly advise against this unless you're familiar with such procedures.
In short, patience is key. The developers are working on a solution. However, these workarounds offer temporary adjustments until the official update arrives.
Hyper Light Breaker is available now.
