Hello there. The new version is available, it's "Prototype-3".
I changed the level to become more compact, so it's good for testing purpose.
With this version, I added passive income system into the game along with in-game time so that it's easy to see when the payout is due.
For NPC AI, I added spawners and have them spawn every 24 in-game hours passed. They're still stupid like before, but I don't want to work on them until I have a proper model.
The direction for this project is starting to get into shape. Though there are a little bit more systems to implement before getting into polishing the game.
