I don't know if you're bothering with updates, but there is a game crashing bug where more often than not, when hitting an eel with my speargun the game will freeze before booting me back to my desktop.
I'm glad to say that I have just uploaded an update to Diver (v2.0) which fixes stability issues, most notably: shooting electric eels will no longer cause a crash to desktop. Thanks so much for encouraging me to finally finding a fix for this. :)
