I came home from a family trip only to find my sister dead. She has left me mysterious messages as her dying wish.

To: My Brother
A・ C・ F・ ?・O

Even in shock, I knew that by solving the riddles I could seek the truth no matter how horrid it may be....

The further I get in solving riddles, the closer I get to the suspect.
But the suspect has a contradicting testimony.

-Will you find the killer?-

I love this game but...

I love Who Killed My Sister, but on level 19, it should be answer or answers, but I put it in, and it says incorrect. If and to put it out there, on the zigzag and letter pattern, a row is left out, and the word zigzag isn’t completed. Please, fix this error, I love this game, it’s riddles, and it’s storyline. I would hate to not be able to complete it. If anyone was able to pass level 19 please tell me so I can pass it? EDIT: nvm I got passed it, it’s bird... but the whole thing is “answer is bird”

I’m almost done with it now though! I’m on 82! And I think it’s kone

Nvm, it’s wink

Interesting in a more simple way

The game itself is simple, but extremely good. There’s a limited amount of content with less than 100 riddles, but each riddle can be thought provoking and fussed over. Furthermore, each riddle is shown to have it’s own answer. I can say this since I’ve solved most puzzles solo, a few with a hint, a few more with 2 hints, and had to show friends to solve 2 in the very last section (86 and 92). 86 was really simple, but I just wasn’t in the mindset. Overall, a fun game with an interesting story. Would recommend
