Thank you for the feedback Charlie!
There should have been a clear starting zone that made it so that your first issue didn't happen, but obviously this didn't trigger as intended so another bug for the list! I agree on the mouse input as well, I initially designed this with the idea of having it as a mobile title so the click and drag is indicative of a touch screen swipe, which I suppose doesn't make much sense on the pc platform, I'll amend this if I work on it further!
Thanks for pointing out the soundtrack issue as well, something's gone wrong there too, probably my fault for only testing the game in editor and not testing an exported build.
In the future i'll see if I can set it up to be an installer or a single executable of some kind - the main game page has some information on how to run/install it but the submission page doesn't seem to have carried that over.
