I hired a video producer to create a new trailer for my game. The shop site and game build have been approved by Valve for the release on Steam. However, I want to have a new trailer first, before I make the shop site public.
I also produced a tutorial video demonstrating all current features and explaining all gameplay mechanics. This video is included in the latest patch which was made public a few minutes ago.
In order to help users understand the user interface, I added a new context help. By pressing F9 catchy tool-tips pop up showing additional information for all UI elements as shown in an example screenshot below.
In addition, I fixed several bugs and made some optimizations and improvements to further increase the game build's quality.
