Hint: You need to find the keys first. Then you can unlock a box on your notebook which gives you the missing hint for the clock puzzle.

I just LOOOOOOOOOOOVE anxiety caused by Kevin MacLeod and Ainars in the morning...

this game is alright but i cant find the last key or figure out the clock puzzle... I give up.

Liked how the game looks and feels.

Those Ghost BC masks where a little distracting.

But this game has everything. If you have ghost. You have everything.

Very well designed.
