Hey! :) Sorry about that, I *think* that might be the poor implementation of the recording steps. I don't know why I went with 1 second intervals, but it did feel ok when the game took away your momentum on rewind. I changed that near Version 1.0 so that the velocity was preserved (making the game way faster!), but I should have altered the steps to .5 seconds or so (I checked it out for my first pots-jam release).
Basically the rewind is a constantly building stack of structs with position and velocity information. With the interval at 1 second though it feels a little choppy or non-precise when the game gets fast.
I could be totally wrong of course and maybe there's an actual bug, but I've not seen it put you anywhere you haven't been at a point in time, what it sounds like you might be describing is when you stop the rewind before the 1 second interval is hit so it plops you back where you just were :)
Hmm not a bad idea some loops could actually be rewind energy boosts :) Most of the game right now is about managing your rewind to maximize your score which is a combination of action and planning (knowing when the best effect is to "split the track" and hit two parts). I also need to play with the recharge rates a bit (also tweaked for post jam!) :)
TLDR: Sorry for the wall of text, but that was some thoughtful feedback you left, so THANK YOU! :)
