I mean actually actually tried to play underfell the website was sorta sketchy but I didn't think anything of it until 2 days later I got a report from my virus detection system.
I know right!!! I was getting so far then... BOOM one wrong mistake and I had to start all the way at the beginning!
You should add chek points
I'm thinking about playing but last time I tried to play underfell I got a Trojan virus which gave me 6 other viruses... just a little on edge.
