Beautiful piece of work, Richard. Love the period detail, the lighting, the feel of the game - both retro and contemporary. The menu system is sharp and the game is effortlessly playable. I think I uncovered some glitch/bug in that (spoiler alert) I worked out I needed 20 amp fuse for lift mechanism. To insert I needed to pull switch in maintenance room to turn lights out. However, once I inserted it into switch, I could not get back in maintenance room and received the message 'blocked', even though it was unlocked. Anyway, that aside, it looks like being another great addition to your body of work. Can't wait to see it finished.
Thanks for the feedback, appreciate it. At the moment, there is the risk that you can leave an object or furniture in a position that means the player can't spawn in the room when you try to enter it, resulting in the "Blocked" message. I suspect this is what you did. If I continue the project, this problem will be sorted out somehow. :o)
