Here is my list. Most of them are more or less one-tap "go right until you die" platform games.
You kinda run or fly using a jetpack. Really gets you hooked on. Great gameplay, lots of things to discover (cool items, vehicles,...). Have to play for a whale to get any good upgrades (or you can pay).
Similar as Jetpack joyride, but you fart. Just discovered it recently, kinda hard to maneuver at the beginning, but you soon get a hang of it. Gets addictive after a few tries. Good upgrades (farting, player,..) and nice graphics & sound too.
You are this whale in the sky. Not much going on, but super relaxing. The music is awsome.
Small birdie that competes with his brothers. Innovative gameplay (press at top of the hill, release at the bottom). Simple. I love the graphics.
1st perspective, avoid and kill zombies. Great graphics, but hard to play (number of zombies increase rapidly).
A game worth mentioning is perhaps . You draw your own character. Cool idea but gameplay is not good, since I got bored soon.
