I already had the first version posted to itch.io...
... when my wife suggested we do the audio recordings for the "mission command" radio texts.
I had already scrapped the code (but that was back pretty quick, thanks to git) and we did it.
She recorded the messages, I removed the noise (cheap mic headset) and edited the sound a little. Then I cut it all up and converted to oggs.. and now there is voice acting in the game!
Give it a try here:
PS: I had a hickup (took me 5 uplaods to itch.io to figure it out) that the game wouldn't take any keyboard input when embedded on itch. The solution (I got it from the index.html of sanoke's jam entry) was to put window.focus(); in the index.html within the handleMouseDown function.
