It's not a bad game, but it's nowhere near as fun and engaging as the original. Players of Subway Surfers Tag will likely enjoy the feel of skateboarding/hoverboarding around the first park (trainyard) and checking off mission sets. You can select one of four different characters, each of whom have their own unique abilities: Jake has electric paint that chains to nearby enemies, Tricky has a fiery throw that explodes in a bigger area, Fresh's sonic wave blasts enemies away, and Yutani uses a slime ball that rolls through enemies like a boulder. It's also fun to earn coins and use them in the Upgrade Shop, spend points to open up new areas, and rack-up rewards for each Arena (location). The "dangling carrot" mechanic works, and you'll want to stick around to see what you can achieve.
But on the flipside, Subway Surfers Tag's gameplay is very basic, which may prove too easy and boring for more seasoned players (even though the combos and missions were boosted in a recent update, perhaps to make it more challenging). The guards now spawn earlier on maps, to imply more obstacles, but the simplistic combat and movement is still there. While the virtual controller works to accurately move your surfer around, aiming and firing your paint isn't as smooth or intuitive, and requires some trail and error to time things just right. While there are some differences in the Arenas, there isn't much variety in what you do for each map (perform moves, collect coins, blow up robots), so it feels repetitive after a short while. While many will applaud the developers for releasing a different kind of game instead of "Subway Surfers II," it's just not too polished, challenging, or memorable.
