Hello Ryuto, very sorry to hear that you have issues with the game, let me try to pinpoint the issue:
- Have you tried increasing the deadzone for the controller? Maybe the right analog stick has a bit of drift.
- Are you using a Dual Shock 4? With a partner's game a similar issue occured with some Dual Shock 4s. The issue could be solved by having the DS4 as XInput via the XInput Wrapper.
If none of this helps, could you provde me with additional information, which controller you are using?
