Hi! Thank you very much for your feedback and going to the extra trouble of taking a screenshot, very helpful! The first thing you mentioned is a feature- the time rewinds if you haven't set a destination yet or the destination can be reached with time to spare. We tried to explain this in the tutorial but will try to reword it!
We are working on fixing the other 2 bugs.
The music was pointed out to us by someone else as well and we found a new one! Will upload the new version shortly- hope you like the new music!
