Despite any faults it might have, one thing I cannot say about Ninjala is that it lacks passion. This game has more heart than a Time Lord, and it’s easy to see how much affection went into creating it. You see it in the characters, the art, the stages, the music, the weapons, and the lore. Nothing about this gives the impression the developers weren’t giving it their all to create a game where players can invest themselves in more than just the gameplay.
And that’s for the best because the actual gameplay of Ninjala might be the most divisive thing about it.
