The version number is perhaps arbitrary, but I go up by 0.1 for each predator that is added. Version 0.7 should be in about a week, and after that each update tends to take about a month. so maybe in a few months?
I won't personally be writing or translating to any other languages as I don't have the time to do that. This may unfortunately have to wait until the game is completely finished and I release the source code for someone to volunteer to do it. I've looked into my options for this like having Google Translate do translation in real time as the game is running, but it's not free so I can't. There are free programs out there though that essentially take a screen shot of the game and translate it if you want to consider looking into those for now.
