v3.0.61 — Idle Spiral Steam update #7149235

- Buying an upgrade no longer resets the spiral. Length is the currency, so a purchase spends it and since v3.0.42 that was being mistaken for the drawn spiral having gone stale, so the whole shape was cleared and a new spiral started growing every time. Now the spiral folds at the point you bought, keeps growing from there, and the bends accumulate into the figure they were always meant to build. - The spiral tip no longer flickers. For one frame after each vertex was committed the tip had no direction to face and snapped flat. Early in a run that landed roughly once a second; it faded as the spiral grew longer.
