This is a pretty neat entry! I wouldn't have thought of combining ninjas and sewers for this jam. Very creative. And the art has a nice, cohesive aesthetic and the UI is very polished. I do agree, though, with several of the other developers that the visuals would benefit from greater clarity. And also like many of them, I experienced performance issues in the browser version. There's a few minor things I could bring up as well, but like the two things I've previously mentioned they've already been covered in other comments so I'll leave it at this. Overall, it's a great game with a lot of replayability due to its random generation
