I LOVE this game. The only thing for me right now is that there is no controller support which is kind of a bummer because controller just feels better IMO.
Edit: I get that it is difficult because of the replay system, but I feel like for now you could just try making it digital inputs instead of analog. So even if you tilt the stick a little bit it goes all the way to the side. You could also do it so depending on how far you tilt it it does it multiple times. So if you hold it a little bit it will press the stick periodically based on how far it's pushed. Sorry if that's confusing lol
