Even though it doesn't really have the best story, or the best gameplay, the cast is absolute fire and even though I don't normally like kids I'd take a bullet for each and every one of them, they were so fun I feel a deep void just letting them go, when they all spoke at the same time and waved their hands in the air, or when they sang together, when they beat their chest two times and then (y), teasing Mowchan, everything about them was really heartwarming and I'm only giving this 5 stars because this is really one of my favorite casts in videogames
Ganbare-gumi ei ei ohhhh

If you want a quick summary: it’s anime the game. Almost everything is voiced, the characters & story are typical, you have robots, the world ending, kids saving the day, the power of friendship, tons of twists and more. It’s well told and I ended up liking the characters despite that style of story telling not being my thing. Also, the Japanese voice actors did an excellent job. The gameplay is the weaker part. There isn’t much there but it’s still basic and mediocre. It also doesn’t help that one hit kills you instantly. There are frequent checkpoints to compensate for that at least. It has some platforming sections with very simple puzzles and fights, including bosses, in between. But the majority of the game is voiced cutscenes. There are some collectibles in the gameplay sections but they’re very easy to spot. Even though the gameplay is the weakest part, I still prefer its inclusion for variety. Being a fan of anime is a strong criteria for liking the game. If you don’t enjoy that style, then the game is not going to change your mind. If you’re fan of the style and genre (the story being the focus), then this is a decent game.

Pretty underwhelming but not bad overall. The game feels like it's aimed at kids which has an endearing touch to it but it also lacks any of the impact you would hope for from the mad lads Uchikoshi and Kodaka working together. The characters are well-designed and can have some cute interactions when the super japanese dialogue isn't neutered in translation. I think the only time they managed to succeed with anything emotionally in the story was at the end with Reycho but there were still plenty of charming moments like whenever a character would awaken their hidden power or when everyone would celebrate with their goofy hand-waving dance. The singing parts were fun too even if they were exceptionally cheesy. Otherwise though the story was kinda weak and the gameplay sucked. A puzzle platformer with very simple puzzles and super clunky platforming just doesn't make for an enjoyable experience, especially with one-hit deaths. I liked the idea of every character having a unique ability but actually using the abilities was always okay at best and awkward at worst. The artstyle was nice but hindered by stiff animations and the soundtrack was pretty good as well.

Aimed for kids but rated T
Lacks any sort and form of polish whatsoever, jumps are clunky and ledges are rough. The gameplay really needed another year in the oven.
3 or 4 characters all have the same power "Shoot [element] forward a short distance. This system is on a cooldown." while others are brainless (Mochan) and one lacks a power at all or only have plot powers(Yuki, Vanilla, Pochi)
The boss fight Pai has can make you leave your 2D plane which messes that fight up
Story pulls the same twist like 3 times

I like the artstyle and the main theme will absolutely get stuck in your head, but neither of those make the game any good.

If you know who made this you already have an idea of what exactly you're getting into.

Yes, World's End Club is developed with kids in mind, you can see that in the very simple gameplay. The controls can be a bit rough at times, but that doesn't take away from the experience.

The world, story and characters are all top notch and shouldn't be passed up because it looks like a "kids game"
