CROSS RUNNER
Cross Runner is an endless runner set in a city. Your character runs on their own, the street keeps coming, and you swipe or click to dodge whatever's in the way: cars, barriers, gaps, the occasional thing you didn't see until it was too late.
The pace ramps up steadily rather than all at once. For the first thirty seconds it's relaxed. After a minute you're reacting more than planning, and the power-ups you grabbed earlier start to matter. A run that goes well feels fast in a good way; a run that ends at the 40-second mark because you were looking at your score feels very familiar.
There's not much to learn, which is the point. It's the game you open when you have three minutes and don't want to think. Retry is instant, there are no lives to wait for, and nothing is locked behind a purchase.
Mouse or touch. It's a little easier on a phone, where swiping is quicker than clicking.
