Mirror's Edge is a flawed but, more often then not, engaging. When you find your flow the parkour meld brilliantly with the minimalist, bright, and colorful cityscape. Ambient synth and more rapid trance-adjacent music match the tempo on screen as you leap and slide. And the story is simple but engaging set up that doens't get in the way of your running. It'sa game with little fluff or flab. Like it's visuals, it story and gameplay has a certain minimalist purity to it.
Thankfully the game saves often though, because you'll fall and die. Or get shot. A lot. It's difficult to gauge distances, and you'll do plenty of leaps in blind faith hoping it's the right way forward as police swarm around you.
Helping you navigate is "runners vision", where certain objects, like pipes or plywood, turn a stylish red against the mostly white backdrop for a directional hint. But it's not a perfect system, and you'll get plenty lost in the maze before you realize what route (or routes) the developers had in mind. Leading to a jerky path progression with few moments of true flow.
Despite that I think it's mostly fun. I grit my teeth and try again. Almost grinding to a rhythm of die, jump, die, jump, success! And the worlds music and aesthetic makes me enjoy spelunking on the roof tops even when I do get lost.
Give it a try for yourself. It's certainly unique.
