Thanks for the feedback. A lot of the audio was placed in absolute last minute and was low priority compared to the other features in the game. I agree with you we should definitely have some audio at the start scene, If we remake the game it'll likely be a bit of ambient noise like leaves and birds to compliment the sort of easy going introduction of the game.
Also, I completely agree with you that the audio loop gets annoying. I always mute the game after about 5 minutes. Unfortunately our usual audio guy wasn't around when we did the game jam and so we had to get someone else who wasn't very involved in the jam to make a loop. We knew it was repetitive but we didn't want the game to have no music. A volume slider would've been a good idea.
Thanks for the video link, I'll definitely be implementing the ideas in the video in later games!
