Reach out to me through discord (tissueinu#2246) and I'll do everything I can to help you out. I'm sorry that you're having this issue but I am completely unable to reproduce it on my own so it's really hard to fix.
Today I'll release a new versions with alternative mappings for the swipe attack to see if that helps.
In the meantime, if you're using a ps4 controller, you could try two things:
- Go to https://gamepad-tester.com/ and check if the square button is being triggered there.
- Use ds4windows (https://ds4-windows.com/) to make the PC think your ps controller is an xbox one.
But as I said, please reach out and we can figure something out.
