Been a while since I've posted this, but I'm hoping to finally find it!

First is the plot.

The main character was to my knowledge a teenager, who had some issues. I don't exactly remember what issues, but something is nagging in the back of my head that it's about his dad (maybe they fought?). He then begins playing a new computer game, and is sucked into the game, alongside several others playing the game.

I don't remember everyone involved, but there was a little sister to someone (might be the main character himself?), who was framed as being pretty useless and annoying. I also remember a girl, probably around the age of the main character, who he fights with at the beginning. And then I remember a guy that's the first to lose the game, but I don't remember anything about him. The sister I mentioned *might* be someone that joined later, but I'm really not sure.

I remember that they're in a sort of forest area, talking about how they don't have any food. I remember a bit (semi) vvivdly about one of the group being like "I wish we could use a microwave/ iw wish we had pizza", and then another one from the group is like "but... we don't have any electricity??"

I very vividly remember that they try to hurt the monkeys in the forest, but they realize that they can't attack them. A fight breaks out in the grup (might be main character and the girl I mentioned), but they realize they can't attack other players either.

I don't rememebr much main plot, but I remember that they're fighting in the game (monsters/ animals etc?), and the guy I mentioned loses all his life... and he then disappears from the game. And that's when they realize that when you die in game, you're logged out, and they're not sure if that means they're also dead in real life.

Throughout the game, they lose more and more of the group. At some point, they get to a sort of tribe in the game, where they meet the creator of the game.

I remember that he's talking to one of the girls left in the group, and he specifically uses the practical example of his technology that ti would mean you could try on clothing fom the comfort of your own home. I don't rememebr exactly why, but something happens to maybe enrage him? But they're forced to leave the tribe, and they're still stuc in the game.

At that point, they're not many left, and it's looking really dire. I think they're under attack from a fort? But when all hope seems lost, the little sister I mentioned bfore shows a way out, I believe? Lik she totally saves the day. I believe that she made friends with some of the enemies that showed her a secret path to escape the game?

In the end, it was revealed that the people who died in game were all alive, but I o't remembr if they explain why they didn't just log in again.

Now, for some general things I remember:

The date is set, and it can't be newer than 2013, but probably even older since I borrowed it from the library. I know the date is set, because I read it at my mom's friends place, and she moved around the first half of 2013, so I couldn't have read it after.

I read it in Danish, but all the names weren't Danish, and it felt like it was originally English (or at least not Danish). The title (in my head at least) is kind of snappy like "game over" or the like. Words that could ring a bell are words like "war" or "commander".

It's one book, and not a series. This one is very firm, as there was no mention of a sequel, and it was very contained.

It was not dark or dystopic or anything. I've trid searching for this a few times, and was often asked if it was crtain series that had plots pertaining to the end of the world, viruses etc. This was relatively light hearted with nothing of the sort.

The cover I remmeber was a cartoon-style. It was black, mayb to show it was night? And there's a group of peopl (probably the main group). I think there might be a campfire, and one of them is pointing in my memoy, like "lt's go that way!" or "charge!"

It's not The Heir Apparent series, Ready Player One, or Jumanji. I've gotten those a few times, but it's without a doubt not them. It's not Virtual War either.

Phew, this got really long... But I really hope someone here knows it! It's been bugging me for so long!
