Hello there!
About the movement issue: are you using a gamepad? The game was developed to be played with one, so if you have the opportunity, go ahead and try It! We may add a keyboard+mouse support in the close future.
About the audio bug: unfortunately, we didn't have the opportunity to fix some audio bugs before the submission deadline. We are working on those, and making progress!
Thank you very much for your feedback, and also for checking out our entry!
