So, as mentioned above, the mod is still alive and is being developed. It would be very rude to abandon the mod on this stage of development. In fact, from the eraliest March-April build and to this very day, there wasn't a single day I didn't work on the mod. So far, everything's okay: maps are being build, bugs are being fixed.
Maybe I'm starting to feel a little bit exhausted, but I knew what I was signing up for when launched JACK back in March. So, in order to finish the mod before winter and make it good I've finally decided to take quality a lot over quantity (the guy who wanted 30 acts, sorry :/).
Here are some screenshots of what I made in the end of August / beginning of September, so expect some more articles in near(?) future.
