Can you continue playing after the countdown finishes?

Just played through this, maybe this will help someone:

If you don't want to wait for the countdown timer to finish you can edit your save (%AppData%\Local\TheFallofLazarus\Saved\SaveGames\TFoLazarusSG.sav) with a hex editor to lower the counter. There is a float that represents seconds left on the timer. Mine was located at 0x53E. It shows up after TApagon and FloatProperty text strings. You'll see a 4 in the hex representing the size of the value (4 bytes) and then some 0x00 bytes later the float will start. Mine has a 0x0A after the float ends. Enter the float LSB first. Use an online float calculator to find the hex for the value you want.

Yeah, sure. I already tried it out. Just dissapointed that almost nothing happened as it finished.

Yes, you can leave the game running and go do other things.

Do I really have to wait 3 hours or so to finish the countdown?

Depens if you take your time looking and searching everything. Using this guide and going "the scenic route" about 6 hours.

In what amount of time do you think it's possible to get all of the achievements?

Thanks for this! Perfect format for helping find a few of those more subtle items!

The items are all realated (ingluding the one in the safe) to the life of the protagonist, but this guide been a spoiler free guide can't say.

Thanks for the guide. I was wondering what those items were for. And even more curious as to how to open the safe. Unfortunately I missed the dog tags in my playthrough. So what is in the safe?
