Thanks for having a look! There is definitely intended to be a smoothing effect to the cursor speed that behaves a bit like a stroke stabilizer / lazy mouse. I wanted it to even the playing field a bit for players with vastly different mouse DPIs and also so the colliders could keep up :D
I've actually had it confirmed by someone else that their cursor was lagging significantly more, and increasingly so. So there's definitely a bug for some people. I've been working on an alternative movement system but its a bit late now!
ty! I listened to pages and pages of different tracks while I was coding trying to find some good fits. I wish I'd had time to do some fading/cross fading too. Sometimes the transition is a bit jarring atm!
