斬撃王：ムカつくけど腕が試される！

I think it's quite difficult. It's a simple game where you just tap enemies coming from the left and right, but if you don't react in an instant, you're done. It's surprisingly tough and the presentation is annoying. There are many types of enemies, so if you even think for a second about 'this one is like this, that one is like that…', your reaction will be delayed and you'll make a mistake. I recommend getting used to it and playing by instinct. Also, after every 2-3 games, a 5-second ad will play. It doesn't kill time, so I don't recommend it for passing the time.

左右から来る敵を倒すだけのゲーム、クールダウンが長めで結構ピッタリでないと敵を倒せない。一度ミスったら基本終わり、敵の攻撃を一度でもくらったら負けです。
