What's a good iOS game for when you fancy something a bit dark and atmospheric, but still proper engaging on a long train journey?

INSIDE is an absolute godsend for those long travel days, especially when you're trying to avoid draining your data. I remember playing it on a train from Budapest to Prague, and the whole journey just flew by. It's a puzzle-platformer, but it's not just about solving puzzles; it's got this really unsettling atmosphere that sucks you right in. The story is told without any dialogue, which I find brilliant because it means you can play it anywhere without needing to blast the sound. Plus, the graphics are stunning, even on a smaller screen. It works a treat when you want something that doesn't need an internet connection, so it doesn't eat up your roaming data. Honestly, it's one of those games that sticks with you long after you've finished it. Give it a go, you won't regret it!
