ぽちぽちシマエナガ

You can tap-tap to raise your long-tailed tit to level 10, enter it in a race, and watch an ad to equip it with a rocket, which will guarantee a win. However... if you close the app, the long-tailed tit resets and you have to raise it again. So, it might be better to play it in bursts when you have time. If you stop midway, you have to start raising the long-tailed tit from level 1 again. This app might not be suitable for people who want to tap during their spare time and continue later when they have free time. It's a shame because the long-tailed tit was cute and the controls were simple...
