first, thanks for trying the game and giving your feedback.
In the description i wrote "your goal is to corrupt an entire 5 floor office." but maybe my phrasing wasn't very clear or it's not what you are referencing to ? either way i change it to "your goal is to corrupt an entire office." so it's more clear. and most of the other things are due to lack of time. everything couldn't be tested thoroughly. the antivirus always being here and the employee helping the antivirus was kind of done so you can't softlock yourself because they allow you to gain skill points (clicking on the desk while an employee is on it give a skill point). As you said at the end it does need a little more work especially on the antivirus part i think.
for the skill tree effect of corrupting another random desk it works when i try it, so maybe there something that causes it to not work I'll look into it thanks !
