Hi, I saw a youtube video for your game and really wanted to play lol, but it seems I need a little help (;o~o)
So the issue I'm having is opening the file when it is a tar.bz2 file. I did look into the link you shared with narimin ( http://how-to.wikia.com/wiki/How_to_untar_a_tar_file_or_gzip-bz2_tar_file) but it didn't make sense to me (;TTwTT)
(JSYK: I cannot code for the life of me and I had like 8 tabs open for "how to's" and "what is" searches because my brain isn't as brilliant as yours 
{I mean, look at you! You made a SIM and it looks great!} and I also was trying to do this on a (Acer) Chromebook because I know deep down that someone else has tried it before and it worked somehow because people create awesome things like (out of context/ not related) VPNs and work around their setbacks in the end. I do have a really old ASUS Core i3 3rd gen windows laptop, but would prefer not to use it because I share it with my family. I don't know what version windows it is updated to because I use my Chromebook all the time. (;^-^) and I also don't know anything about my CB because I didn't buy it. Sorry, I know that's not enough info for you.)
If you don't mind helping that'd be great, but it's okay if you don't or can't. I know that a lot of people already tried to download your game using Chromebooks but couldn't because that's just how it is with them, but I really wanted to try still (; v ;) Thx! and keep doing your thing! Plus Ultra~
