Open game files location (right click the game in steam library in left column, Manage -> Browse local files). We need file ...\steamapps\common\Beat Da Beat\Beat Da Beat_Data\Managed\Assembly-CSharp.dll"

https://github.com/dnSpy/dnSpy/releases
(choose dnSpy-net-win64.zip)

- Open dnSpy
- Open Assembly-CSharp.dll in this program (File -> Open)
- In left column will appear Assembly-CSharp
- Then need to go throw tree in left column: Assembly-CSharp -> {} - -> PlayerShip -> MoveWithMouse() : Vector3
- Click on "MoveWithMouse() : Vector3"
- Need to change the 18'th line of code:
- Right click on code -> Change method (C#). Window will show up
- Change code by removing the line and replace it with two this lines:
- 4 is your sensitivity. You can change it as you want. The default sensitivity is 20, but for me it's tooo much. (Don't forget "f" after number 4 or other number. It is needed). E.g., if you want sensitivity half the default, it will be "float sensitivity = 10f;"
- Click "Compile" in the lower right corner
- Then File -> Save module -> Ok
- Restart the game (if your game is running)
