The wide steering is intentional, an attempt at mirroring JSR's skating physics. It's why I've added a drifting mechanic (tap back, then steer) for tighter turns. I can reduce the steering circle, but I don't want to do that too much.
I think reducing the steering circle would benefit quite a lot actually. And about the way to dash, maybe make it activate by holding down the button instead of having to spam the button. It makes my hands cramp a lot. Or i guess maybe make it an easy mode like mario odyssey's assist mode.
I've made my choice. I've found the THPS-style steering satisfactory, so it'll remain the same, but I'll make dashing easier: press at the right time, then hold for a time-limited auto-boost.
