This game has such a strong feel to it. There is something about manipulating a head and seeing everything going through it. I recommend not being proud and allowing yourself to use the help. Not only it helps you complete the game, but the indications are still within the thoughts of the character which you can only want to more about it!
It's a lovely experience, the puzzles are fun, and the physicality of some of the actions - which I won't spoil but I really liked cutting the stuff and setting stuff on fire hehehe. The game is also beautiful and sounds great. Like the way the sounds when you zoom in and out interact with each other and also as you travel around the head ... Big brain. Literally!
