Thank you for playing my game! It looks like there might have been a parsing problem I failed to check while developing. The terminal is really sensitive to extra spaces typed and that's what I'm thinking must have happened. It is also possible that the game completely skipped the tutorial after running a 'run' command and defeating the tutorial antivirus in one shot, therefore skipping to the next level with no warning. The game was designed to allow players to play multiple rounds to defeat antiviruses and after defeating all of them, it would jump to the next level and reset the entire terminal.
I appreciate your feedback and will look into fixing these problems.
