★★☆☆☆Not Yuxin6/4/2023
I don’t want the minigames

The ads are overwhelming and also the minigames are unnecessary, I only downloaded the game because I wanted to manipulate people’s death and kill the people but half the time it’s a whole entire different game, and everytime you beat a game there’s L on the computer so there better be something that has to do with L for it to be more like the Death Note anime. Also I want more of the death note game mode where you can write people’s name and kill them. But overall it’s an ok game. I don’t recommend it but if your feelin like killing just like me then go for it!

Okay, but too boring and easy

This game is overall pretty decent. For me, the ads aren’t too overwhelming and it’s pretty fun. But the worst part is, it’s never just about the writing names in the death note part. There’s these cheesy, insanely simple levels to go along with it. This would be fine if they were more exciting. I can literally finish these levels in ten seconds, and most of them are just shooting two demons out of the sky, or writing two names in the death note and then the level ending. Now I know, writing a name in a book and then instantly killing someone is a simple thing, but there are so many things that can be done to make the game more interesting. If your someone who loves easy games and craves death, then this is for you. However I would not recommend this to someone who wants a challenge.

i love the game but it needs fixed!

this game is super fun, but there’s a whole bunch of lag, and it doesn’t let me click on things half the time.. such as when i was picking between two people to kill, it wouldn’t let me pick the person. about the lag, i know it isn’t my internet because i can go on everything else without any lag whatsoever, but whenever i go to this app, it lags WAY too much for me to even do anything.
