I've edited your post to include your text as translated by Google Translate - I'm afraid that I don't speak Russian, so if you want to be understood, English is your best choice. I've also merged the thread to the comments on the 1.7 update, as it primarily relates to that.
Anyway, I'm sorry you seem to be displeased with the updates made to the game eight years ago - but I've put a lot of love and attention over the years into trying to make the game as good as it can possibly be, and part of that has been to try to ensure that all of the elements of the game have a functional purpose. In the versions prior to v1.7, there was too little difference in difficulty between the Hard and Easy modes for the various levels, which meant (as you've said yourself above) that the Easy mode was still very, very difficult, but once a level was completed at that level of difficulty, the Normal and Hard modes were close to being simply repetitions of the same process. That was never the intention of the game layout, and I think that the current balance is much, much better.
Of course, as you've played the game before, you will find the Easy mode much easier if you've already played through those levels in an earlier version - but you have a bit of an advantage there as you already know how to play! Oddly enough, just a little earlier today I watched a player new to the game struggle try after try to complete some of those stages in the Easy difficulty for the first time, so I really don't think it's true to say the game's become "easy" by any reasonable standard - but I do hope that it's now at least a little more accessible to newcomers than the first few versions were. I certainly don't think there are many people around who'd be able to pass through the Easy mode for the first time even now without a
lot of failures along the way.
Plus, of course, a player good enough to have completed all of the Acts with a Perfect grade has an additional reward in the form of the Act Editor, which hopefully is quite a cool prize for anyone with the required level of skill and perseverence!
I personally think the changes made since the 1.7 update have helped to make the game much better balanced, and much closer to the game I wanted to make when I first started work on it all those years ago - you need to remember that the game isn't tailored to your skills personally, and as the first game in the series, needs to have a good learning curve, rather than being so difficult that it's only playable by existing players. If you're good enough to find the Easy mode unchallenging, that's great - and like I said, perhaps you should try
Afterlife 3, which certainly has a much more brutal level of difficulty for players already used to way the game works, plus a
lot of new things to explore and discover.
In any case, I'm trying to be helpful - whether or not you understand the reasons for those changes, it's honestly really nice to know that you like the game enough to care enough to post about it eight years after the update!
