Do you remember that horrific animal-destroying child from Pixar's Finding Nemo? Now imagine you're a fish living in the home of a similar child and you're presented with one opportunity for escape - the river just outside your window. Would you take it? Even if you knew there was a slim chance of survival? Is the risk worth it for freedom? Philosophy aside, you can help Yello in his attempt to escape the clutches of a crazy young-girl by dashing along a twisting and dangerous river-rapid.

Chasing Yello is ostensibly a coin-grabbing score-hunting 'endless' auto-runner that distinguishes itself from similar titles like Temple Run by sticking to the vertical movement, adding in-lieu of direction changes, a variety of multiple paths that can reward or punish you depending on your quick thinking and reactions.

Swiping will make Yello jump or dive accordingly, with tilting moving the feisty fish from side-to-side. Coins can be located on, above or below the water surface, so you'll have to balance collecting as many as possible (along with bonuses for combos) with staying alive.

It's a delightful experience too, filled with bright and colorful designs, while the expressions of terror on Yello's face provide a lot of motivation when it comes to avoiding his final fate.

Where Chasing Yello stumbles is in its sense of progression, making subsequent purchases to upgrade power-ups or give players a second-chance very pricey, while its challenges remain fairly tight-fisted when it come to rewards, so you're stuck grinding game after game to eke out better scores.

If nothing else, Chasing Yello isn't lacking for challenge or variety in the way it presents its hazards, making it an easy game to keep coming back to. Unfortunately without a sense of momentum in your progression this can become tiresome and with any luck updates will address this issue.
