Everything is there to solve the puzzle (the more time you get stuck more clues you have), I loved it (it would be nice to let the player that the code is a 4 letter code), I was starting to type the whole thing after a pass it tru ceasar cypher, then I reach the end of the text box and I realized something like that would be to hard and tiresome and then I saw the clues, too late I lost my first attempt, but the second one was easy (I try to use brute force but no words came out of it so then I realize the pop ups had a number and then the hard part was only looking for the 4 letter code, great game I really loved it (I hope dumb people dont steal you a place on the first 100)
