It feels like there's a LOT going on in the background that I don't understand- I'm not sure why my teammates are taking damage or why they attack when they attack, and I didn't figure out what most of the powerups did until the very end of the game. I still don't know why stamina was suddenly a problem in the final battle when it was basically a non-issue before. I also don't really feel the described genre fakeout- I was promised a ninja game and that's what I got. Overall though I think this game is leaning hard on a few specific references I just don't get.
Overall, it feels like classic Fistmaker, and it's pretty cool that you have such a well defined style year over year that's very apparent even in wildly different genres.
The ending is funny but it feels like it's missing a line. It technically has a punchline... but it needs a denouement or explanation to finish off the joke.
