Yea, I did it! Finished the game:D I got stuck a few times but I couldn't wait for walkthrough. Great game!
What's interesting, quite by chance I found girl from 'Daymare Cat' and gave her something:)

The game is amazing! It's quite hard but I don't think it's a reason to give it low rate. I could even say that in my opinion difficulty level is perfect. The game is challenging but not impossible to complete.
Probably that was a matter of luck but I reached the third panel-puzzle without any problems. Indeed, the third puzzle is very hard. I gave up on first try. Each time one extra dot left in the center :/
But the whole game was so interesting that today I tried again and I don't know how but I solved it after about 2 minutes. That was miracle :D
Anyway, I agree that the walkthrough will be a good idea.

P.S.: Pozdrowienia z Tychów:) Czekam na twoją kolejną grę
