to make the best ending get both eve and molly endings,get to the last save, make sure you have the 20k, work at tech support, get the virus thumb drive, give dad the 20k and go upstairs when you come back dad will go do the paperwork, now install the virus thumb drive on dad's computer, go to sleep, you'll get grounded, just sleep until dad unlocks the door, he will go fix the computer, fuck both your mom and sister, sleep, congratulations! you got the best ending :)

JRVthatsME @ 2018-12-26 04:04:13
Ump, I can't just get an error sound when I try. it just won't do it. playing on chrome, if that makes a difference.

How do you do the box puzzle in the garage AFTER you get the running shoes to push the dark brown box?
Just A Gamer @ 2018-12-22 00:50:21
Edit: Just adjust the zoom to 110%, nothing else.
Help @ 2018-12-22 01:37:51
Just A Gamer, you need to restart with it at 110%
Robert @ 2018-12-21 22:50:12
I tried on Chrome and Firefox but the town glitches the game. What a shame, I'm so glad to see another NLT game. The female models are hot and bet this game would be awesome.
Kyre @ 2018-12-21 22:39:41
Another promising game, but the town seems to have an error. Shame, seems like a simple fix, but makes it unplayable.
damn @ 2018-12-21 21:30:58
I was excited.... town is glitched. not playable.
WeLLo @ 2018-12-21 19:37:10
Town is bugged gives me null whatever error and I can't save game so pls fix.
