New Year's Quest

A couple of days ago, I succumbed to the general New Year mood and decided to do the New Year quest. Actually, here he is .

I spotted the principle in the quests of Dmitry Astapov aka _adept_ : at each level a task (text or picture) is given, having solved it, we get a password to the archive, which contains the next level. Archive zero (quest.zip) without a password.

The tasks turned out to be different - partly on abnormal programming, as I had planned initially, partly on shrewdness. Since you can squeeze out a lot of hidden text options from a text file, and even more so from a picture, with proper desire and ingenuity, the correct password at all levels is marked with the prefix “pwd:” (you must enter the password without the prefix).

I hope you will like it. Holiday greetings!

PS The presence of bugs is not excluded; write in a personal, correct, update.

Update. A mistake crept into the puzzle of level 6; fixed, quest.zip archive updated (archive size should be 21501 bytes). If someone has cached the old version, you can download it via the link tc-alchemy.progopedia.com/quest-patch1.zip
