Loop playback finally solid.

Significant bug fix:

During the jam there were a significant number of glitches with the playback for some of the character loops particularly on the later levels which would end up with all the characters loosing their minds and walking into walls making the last levels all but impossible if they started to go wrong.

With this fix I'm finally happy with how solid the playback is, which means the core mechanic is finally reliable - Do let me know if you spot any strange behavior, do remember though, they replay input not positions, so if the environment changes so will their path!
