Oh thank you so much for your feedback!!
Can you let me know at what point in the game you ran into the error if you remember?
Also yes the game isn't complete this is just act 1 which is all setup. Most of the gamified elements come into play in act 2. Re: the assets yes they're just what we could find for free but we are working on trying to get custom game art. I will look into the error and work on adding some more sound effects so that the few times that sound comes into play it doesn't feel out of place or random
