Ok, first of all: To make spoilers you do this without the spacesStarker said:The tutorials are not there just to teach you the rules, they are also there so that you can experiment with them and test the rules to figure them out by yourself. The game is gated away metroidvania style and the knowledge in your head is the key to unlocking shortcuts and access. That lack of handholding is probably one of the best parts of the game. The game gives you all the tools that you need -- it's up to you to find the knowledge and use it.

Also, as far as puzzles making use of the environment is concerned, there are puzzles that require you to frame a puzzle a certain way in the environment, there are puzzles that use reflections, there are puzzles that play around with colour filters, there are puzzles that use sound, there are puzzles that use shadows.

Dismissing the game as having one single puzzle that could've been done as a smartphone game is one of the more ignorant criticisms of the game that I've seen bandied about. Drawing lines is just the input method and the puzzles itself are far more clever, far more varied and far more involved than that. If it was a smartphone game, it wouldn't exist.
Anyway, whether you'll like the game or not probably depends on whether you like puzzle games because of the story and see puzzles mainly as an obstacle in way of the content or whether you like puzzle games because you like the satisfaction that you get from solving cleverly done puzzles and see nothing wrong with the reward for solving puzzles being more puzzles. If it's the former, this game is probably your anti-game and you should stay away as if it was a pit of cacti with those barbed needles that stick in your skin, but if it's the latter, chances are good that The Witness is so much your jam that you can just jump right in and roll around it all day long.

not what you did.
Second of all: I agreed with you. I think you meant to reply to the guy that I was replying to.
