It's just a Windows 95 gag along with the other Windows 95-esque goodies surrounding this game. Sorry if this has been an issue.
Would you mind e-mailing the AVG warning to support AT astrojone DOT com? We'd really appreciate it.
Got it!
It could be a .hlp file :)
No worries, the game is really cool (spent some good minutes looking at the office window =P) and the BGM sets the correct mood!
I just wish it could save my progress, because I had to stop playing it and when I came back, had to start all over again.
Keep the great work up!
