Centipede: Origins, which is inspired by Atari's classic Centipede game from 1981, throws you headlong into an endless battle between bugs and garden gnomes.

Your mission is to arm yourself and protect your garden from the attacks of pesky bugs, using six upgradable weapons and gadgets. Y'know, grenades and time warps and that sort of thing.

There are four levels available out of the 'box' - Bumpkinpatch Gardens, Bumpkinpatch Aerial, Tarpit Excavation, and Valley of Flowers - but you can purchase more as you progress.

Chasing Yello is an endless-runner and a semi-sequel to physics-puzzler Saving Yello. In it, you have to help a small fishy successfully navigate an obstacle-filled creek in order to escape from his seven-year-old owner.

The creek is filled with burning logs, piranhas, dangerously sharp rocks, and a range of other obstacles that can ruin your day.
