Sorry for the late response but aaa thank you so much!! The rail grinding thing was actually something I caught and debated fixing it (grabbing had a similar issue that I actually did fix) but I ultimately decided it was harmless enough.
Also yeah I'm def considering expanding on it! Got a smalllll update in the works and I think adding more features (especially extra tricks based on input direction) would be fun. There is actually a safe way out for that pit issue by holding up and pressing the flip-trick button for a lil extra air, BUT I gotta admit it's not made super clear so that's something I gotta fix. Again, thank you so much for the feedback and will keep it all in mind!
