^ Yeah i noticed problems with keyboard too. It's kinda slow. Can't dash sometimes and if i type fast some moves are not registered at all, i hope that it will be fixed.
It most probably isn't a problem with the game, Rider. As I said, your keyboard is most probably having keys ghosted out when you press a few simultaneously while playing.
Do the following test:
Press and hold both Shift buttons ( Right + Left ), and type the following sentence:
"The quick brown fox jumps over the lazy dog."
My result is "HE QUIC BROWN OX UMP OVER HE Z OG". The missing letters are the one that are susceptible to ghosting.
