First, we have: automatic doors that open when you walk into their range.
The same doors can be closed/opened with access cards, here is one such card:
Using it, you can lock the doors. There are three security levels (three colored cards), each color adds a new level of security to the door. This helps keep the monster out.
We have an inventory system with 8 slots (controlled via the mouse wheel), with which you can pick up, use and drop items. You can even use items with other objects, like putting duct tape on something!
For the items, we have a fully functional vending machine. As you can see, all of the usable items are able to display their names and two info sections on the HUD.
We have two view modes in the game, one lets you see your near surroundings in black and white, the other lets you see electricity, other types of connections, and you can see much farther with it, although in significantly worse quality.
We have a power supply system, any item has the ability to run on electricity, there are power supplies that can be chained together, and switches to trigger each individual item, or multiple items at the same time. With these, we can build a full system, perfect for puzzles. Here you can see power cores that can be inserted into the sockets, which provide power for the circuits. There are other items that can be picked up and thrown as well.
The latest addition is the ability to climb into air vents. This has no animation or transition yet, so it looks weird, but it is also fully functional.
We'll try to update more frequently, as we're moving faster and faster in development. See you next time!
