What's a good iOS game for just, like, mindlessly collecting stuff and seeing it evolve into something cooler?

Alright, so if you're looking for something to kill time on the train, Steering Wheel Evolution might be your jam. It's from HOMA GAMES, and the concept is dead simple: you merge steering wheels to get better steering wheels. It's one of those games where the dev team really thought about the dopamine loop – constantly unlocking new stuff keeps you hooked. From a technical standpoint, it's not pushing any boundaries, barely uses 60MB of RAM on my iPhone, but the art style is clean and the UI is intuitive. No spaghetti code situations here, I hope! It's got that classic 'idle game' vibe, so don't expect anything too deep. But if you need a distraction while you're waiting for your code to compile, this will do the trick. Plus, the physics are pretty funny when the cars start moving faster.
