If I guess I would say 3-25-17- 3-30-17.
Well it gives you a little time to clean up and prepare. I'm making you a main menu image so its not the same as the main game. Using the To Hell With You image you supplied. Shared this on fb a few times its getting some great feedback. So now lots of people know this is coming. I shared it into a doom fb that has 13k members.
Exactly if somethings don't work out the next update could fit it in. Dude you need to do the final polishing stage on level 2 and 3! I don't think you want to wait to late to start doing it man. I would start asap. But both levels look very nice I just noticed your notes that say level 2 and 3 need your polish stage. I'm going to send you the updated wad file with the main menu image today in pm. Keep an eye out buddy.
Thanks for sharing buddy means much. Yeah I got your message we can use that as the menu. Thanks! Yeah man I'm really short on time but I'm going to be trying to finish polishing those two levels this weekend. Feel free to give me any ideas what to add, change, or anything.
Sounds like a perfect release date! Oh no worries sure maybe in an update. I will work on something for that. Yes like Jay says helping you prepare for release. 
Yeah I didn't mean in any bad way just short on time and a lot is clogging my brain so "new" stuff added is a lot to take on. Do whatever you want and submit to me. Would be awesome.
And try not to delay it.... But on the plus side for you...you never released a release date publicly. Except on this thread and it was like a "aiming for" rather than a confirmation. Take it easy keep up the hard work. On everything you been doing we will definitely appreciate this mod.
Glad you like the story its not finished I like to think the hole story will actually add something to the maps. I'm writing a full story that's just the gist of the story. I have so many plans and less time hehe. So things take me a lot of time these days. Back when I was younger things would get released with the quickness! Bang bang bang.
