Work is now being completed on the final areas of Part 1, and initial testing will begin shortly. There have been no coding challenges lately, work has been primarily focused on world development; assets, scenes, lighting, sound. Following the last scene and its missions and dialog, work will shift to pre-release mode.
There is still plenty to do in terms of voice acting, end to end play testing, and polishing. With 4 months to go, there is plenty of time to get this done, and if it is completed early enough, Builds of the game may be released to play testers on YouTube who are interested. If this occurs, there will be announcements and links.
