I can't really say much other than the lack of music was very noticeable outside the sound effects. You need to get music. Go on Fivver for music or contact a musician directly for the style you are looking for. Nothing you can do to the gameplay other than adding a timer. Some noises for a voice for the MC would be cool as well. The only thing I can find fault with is with the lack of sound design in certain areas. Looking forward to this.
