Im probably blind. But I can't find teh code for the safe. And there is apperently another potion (which I don't even know which theme it represents) + a few more images... Probably Im just blind. But yeah games is interesting I like it. Hope you will do even better in your next projects!

It gets split up in the game so you have to connect the three numbers together, by talking to the women in the lab, and by finding the last one on the notes
Then the potions which there are three, one is in the safe too so if you can't get that open you'd be unable to get the third one
If you need the answer for the safe combo, I did put it in a note document in the zip called ImageUnlockGuide, so if you open that you can just put in the number directly
And thank ya, next one will be bigger with the item finding and less of the puzzle element
