This is a great game. But at least watch videos of portal 1 before playing this, the story might not make sense otherwise. Good puzzle content, makes you think. There is some talk of robots killing Chell, the protagonist. There are bombs, turrets, neurotoxin, deadly goo, being crushed, and not-so-deadly lasers. But, you don't die for real, you respawn. There are some minor curse words such as damn and hell. Also, there was some controversy regarding a comment that says, "You are adopted, and that's terrible". You can also create your own test chambers and play other people's , and it shows the author of that test chamber. One person has the username, "d--kbutt".
