Lunic: Possession

Who is Lunic?

Somehow you managed to get trapped inside a school that has been abandoned since one terrible accident. Looks like in order to unlock the exit you need to put certain pictures inside frames. But who came up with this kind of challenge?

You need to find pictures that are hidden behind locked doors for which you need to find keys. Every playthrough everything is spawned differently.

UPDATE:

• Reduced pictures amount to 4
• Reduced difficulty a bit
• Made game's goal clearer
