Ninja Slash

 is a badged game on Kongregate. It was developed by doopop.

Gameplay
You are a ninja, cutting down waves after waves of zombies. Do combos by slashing a whole lot of them in a row for a higher score.

Types of Zombies
There are 6 types of zombies.

Zomblings
The weakest, most common one. Simply run into them to cut them down.

Sweepers
The thin ones with a straw hat. Run sideways in front of them to slice them.

Goliaths
The huge ones. Slide under them to cut them from below.

Lankies
The ones that look like they come out of a pot. Jump into their faces to decapacitate them.

Fatsos
The fat ones that simply sit on the ground. Run into them (like zomblings) to cut and bounce off them at the same time.

Berserkers
The hugest one that occasionally charges at you. Avoid them (the thunder/purple scroll allows you to slash them, though).

Non-zombie Slash-ables
You can also slash bamboo trees and signposts by running sideways, like for the sweepers. There are no points for that, but it looks cool.

Tips

 * This game is basically a series of repeating patterns. It helps if you are familiar with these patterns as you would know, for example, if there was a scroll behind that goliath or if there is a fatso at the end of that rooftop.
 * If running for a certain score, aim to continue your combo as it gives more points. When it gets very fast, you don't have time to think. Prioritise survival.

Trivia

 * Prices were lowered A LOT after people complained that it was too high. This is probably due to it being an online game where people would play it to completion, rather than a mobile phone game where you would not get bored of it too fast because you would play it in short periods instead.
 * Many complained that it is basically a copy of Subway Surfer. It is actually better, because zombies.
