さよう

おおお　英語やん！

thx :D
I am thinking about next game.

I really like this game, i feel though it's hard to attack sometimes when you are above or below, and when you become level with enemy you've accidentally touched them, it's lovely, make more!!

@Intoxicatious
Yes.Penalty is nothing.However, as long as your Shuriken exists, the following Shuriken cannot be thrown. The number of the Shuriken which can be thrown at once is one.
@Keevor
To be sure, green Green Ninja is dangerous.
However, since there is a measure, it is doing in this way.
@Darkrain
thx :D

Is there no penalty to spamming shurikens?

One suggestion. make the players Katana bigger than the enemies. I usually found that the enemy would always win in Katana fights.

This game is insanely hard for me!!!! Lol. Nice job! Very small res. Mobile?
