I have the PC version and when I press A/B/C (don't know which one) it registers it but then opens the menu on like the next frame, pausing the game. The other 2 buttons work as intended. So I can only spindash with 2 keys. I tried to reassign one of the keys on my keyboard to another key with a third party program (sharpkeys), but it doesn't register consecutive inputs of the same key fast enough so it's basically the same.

I almost broke a ps4 controller because of that

OK, so apparently this can be fixed by using an older version of the game (the third spindash button doesn't pause the game anymore). I'm using version 1.3.5. Is this allowed?
