Nope, the whole game with (almost) full content on PC is like 40GB so I would expect mobile could be somewhere 20GB or less.
The game mostly use procedural generation (aka tilesets) so it won't expand its size as much as regular games.
Yep, that's a clickbait title. People forgot or don't know that Samsung is just a part of long-term security updates. If you run on Android 11+, Google will also involved with your phone security updates as they are the one making the modular system updates that are separate from OEMs.
Also "will no longer get updates" is totally wrong, that's minimum guaranteed updates, not maximum updates that actually happen with your phone if you ever own a phone for really long duration, especially with Android 11+.
You can check most Android phones these days uses a thing called "Google Play system update". As your phone gets higher Android version if possible, the more modules can be updated. And with Galaxy Fold running Android 12, you can update as deep as critical components like ART and many others without Samsung ever involved. https://android-developers.googleblog.com/2023/08/latest-artwork-on-hundreds-of-millions-of-devices.html
Blame Google for making sh*t OS that is hard to update (they fixed that a bit since A10+), not really Samsung's fault.
There is no P2W element in this game, and the game is purely skill-based.
The game is indeed janky with the parry and cancelling mechanics. Once you are familiar with those mechanics, it's really fun with the holdchecking to see who have bigger brain.
The game was designed with asian elements so it might be weird if you are westerners.
