Here are some news about the work done:

Several new models have been added: new types of walls, cabinets, books, boxes.

 A version of how the classes will look in the game has been made. The map has been partially completed.

The plot was almost completely thought out, it only remained to bring everything to mind.

Now we are working on creating a map, arranging things and decorations, the map will not differ much from the alpha version.
We are also working on creating a demo video.
