Try to complete all the puzzles in the game Doors: Origins and don't give up! You have a lot of doors and objects around them. Every door need to open, having done a lot of steps before that, and finding the key. After the door opened - you are taken to the portal and go to the next level more difficult. Main advantages: the opportunity to not only click, but to drag something in reality (twist the handle, turning the pages of books, ripping paintings, open the door to the side), nice music and graphics.
