As the others already pointed out the  title screen absolutely has to be skippable. Especially since your game is quite difficult, and while dying a lot to a game can work the title breaks the flow a lot. I love the 8-bit look and feel of the game (I don't know if intentional or not but i think the difficulty also fits quite well with other NES games). I have one bug to point out and that is that when enemies try to pathfind to the player, and end up hitting a wall, they get stuck forever. If you were to fix these, and maybe make the frog ninja just slower, instead of coming to a dead stop when using the sword i think you might have a great retro style game on your hands. The problems do sadly kinda kill the experience a bit tho.

I think I'm not alone in saying that that intro text absolutely has to be skippable. The player will die a lot when trying to figure out the controls and having them sit through 10s of text each time is guaranteed to turn people off - I couldn't really get into the game because of that simple mistake.

Looks and sounds very nice once in the game :P

Good job on the submission! I wanted to try playing this game some more but with only one life, a stubby attack and having to sit through that wall of text when the game starts I was only able to give it 2 or 3 shots. Even a quick restart rather than kicking the player out to the titlescreen when they die would be much appreciated.
