Autorunner top down shooter is an interesting idea.
You credit music on the game page, but I don't hear any music :( -- I'm running the linux build.
I also had trouble with music on my game, but got them working after using ffmpeg with:
ffmpeg -i audio_in.wav -ac 2 -b:a 160k -ar 44100 -acodec libvorbis audio_out.ogg
I think you're on mac and can do that from your terminal, replace audio_in.wav for you mp3 or music file.
