I downloaded the demo like an hour ago. Day 1 went fine, it lagged a little but my laptop's older so that's normal. I put two people in quarantine.
On day 2, I checked the first survivor in quarantine. The game let me put him in the block easily. Next, I grabbed the tools (flashlight and scanner) and went back to examine the second person. When I opened the tablet to input their symptoms the game stopped immediately. Just didn't let me input anything - no scrolling, no clicking.
I restarted the game, and the same thing happened (I did exactly the same too).
I restarted the game again, this time after grabbing the tools I went to the normal examination place instead of checking the other person in quarantine. Everything worked fine until I opened the tablet - game stops working again.
I expected the game to keep working like before, but it did not.
I don't really know my hardware specs but since the first day went as expected, I think they're fine.
