Congratulations on your first game on Newgrounds!
It's a simple platformer with nice graphics, the frog is especially funny. It needs more polish.
it's a weird mechanic that you respawn when you hit the enemy with more than one life.
I don't know if it is only me but the keys can't be pressed together at times making that the character just jump on place or only run.
mayor problem: at the end of the game it gives an error about embedded youtube.
hope to see more of the ninja frog!
