I had one team mate.
And I'm currently trying to fix that bug, I don't know why it's being unreliable. I'm hoping to have an update before I start work today :P
First room you have to press E on the main system unit, should provide power (turn lights on). Then you wave the card over the green section.
I'm currently trying to improve the text cues too since apparently the "pad" isn't clear for everyone. I'm trying to work out what is the best way to handle it.
It's not a horror game, just a low lighting. The first part is a "power failure".
Ha ha, yeah, I'm now having trouble understanding where the "scanner" is for the second bit. You gotta make it crystal clear for players.
My other advice would be, for stuff like keycards etc, most (if not all) games have it as an inventory item. Using the physics component to hold it suspended in mid air in front of you doesn't quite work and looks and acts a bit clumsy. So I dropped it again, it got wedged under the computer unit in the second room (lol!) and even though it was visible, I pointed at it and clicked but couldn't hold it again!
Hahahaha I'm loving it!! I was thinking of making it an inventory item to be honest. It's easier, I was just debating about the feel of scanning but at the moment it's not worth it. The physics component also has some strange mechanics with frame rate. I was testing it and I could yeet the card out of the map.
The big area is the "scanner" the pc is the system you use to scan. So put it on the disc, then interact with the pc. I'll work on making that clearer. :)
