I've decided to add some visual indicators to compliment the audio cues in my games. The cues are there to warn the player of imminent danger and I realized, if the player doesn't have access to audio, it would make the game quite a bit harder to complete.
Now it's also time to start seriously working on the sountrack, which I both look forward to and slightly dread... I do enjoy creating music, but I find it much harder to tell if what I've created is actually good, compared to drawing a picture. It's also harder for me to visualize the finished product, because I can't hear the audio in my head the same way I can see a finished picture... there's a lot more experimenting to find something I like.
