i used to replay this a lot as a kid. remember i would struggle on some of the puzzles and especially towards the end trying to shoot those monsters. I'll replay it now and see if i do any better. XD
also never watched the mist, but i think the plot was good enough on its own to understand.
update: started replaying. some of the mini-games/actions specifically the toy car or pausing the tape are still annoying. however, it wasn't as difficult as i remember it being. i memorized most of what i had to find anyways to progress from replaying this so much as a kid.
I think it still holds up well for an old flash game, it's maybe an hour of entertainment.
