About Kill A Million Rats

The Rats are invading the forest, and you are the SPIRIT OF VENGEANCE! Your objective is simple: EXPLORE the valley, EXPLOIT its resources, EXPAND your village, and EXTERMINATE the endless horde of Rats!

You are a powerful Spirit of Vengeance, capable of cutting down thousands of Rats with your magical powers. But you cannot do this alone: you will need to harvest resources to construct buildings and recruit a variety of allies, in order to defeat the enemy and achieve victory!

Explore a randomly generated world! Each time you start a new game, you will discover a unique combination of powers, resources, enemies, buildings and allies. Build up your village then protect the villagers from the forces of the mighty Rat King! The rogue-lite nature of the game ensures that your options and challenges are always interesting and constantly evolving.

Save the innocent animals of the forest and rally them to your cause! Adorable bunnies, mice, cats, dogs, pigs, stags, bears, monkeys, birds and more: each and every one is lovingly hand-drawn and brought to life by Nerdook in his signature cute & colorful style.

  • An action-packed blend of the base-building and strategy genres.
  • A procedurally-generated world to explore in each game.
  • A lot of Rats to kill in many satisfying ways. Seriously, there are a lot of Rats.
  • Dozens of powers to choose from: upgrade each one of them to kill even more Rats!
  • Intuitive controls, supporting keyboard, mouse, or controller: it's your choice!

✦ AI summary

Players praise the game as a fun, bite-sized roguelike that creatively blends town-building with vampire survivor-style combat, with many noting the developer's consistent creativity across their catalog. However, common complaints include a cluttered UI, overwhelming mechanics that feel poorly introduced, heavy RNG that creates balance issues, and insufficient content relative to the price point, with some finding the early game's constant interruptions frustrating despite appreciating the core concept.

Fun little game. Not something you're going to play for hundreds or even dozens of hours. Getting all the achievements shouldn't take more than 20 hours or so and probably less. I was happen with 7. But it's got a fun combo of mild town building and Vampire Survival type auto combat. Never played a Nerook game that wasn't fun and different from any other game I've played. Bite size fun at a bite sized price. Play it.

This feels like a gamejam game that a team of people just shoved every little broken mechanic into that they could find, there's a billion things happening at once, absolutely all of which feel very clunky and badly introduced, the combat isn't fun at all, the screen is way too full with the horrible UI and the railroading at the start with the constant freeze frame interruptions literally every 2 seconds makes me want to punch the screen. These guys took absolutely every element of good TD and survivor.io games and said "nah".

I'll give it a positive review more as an incentive to Nerdook. Like many others here, I've played his games since Kongregate times (and probably have literally played ALL of his games; from Kong to Steam), I've always thought and still think that he's one of the most creative indie devs out there who isn't afraid to try different things. So I'll give that "free credit" to him. My criticisms, though, are also pretty much in line with many others: the game is fun, it has a lot of potential, but so many rough edges that detracts from the FUN you could have. Yes, it is a roguelike game and as such randomness is a thing. I understand that. But RNG plays a big role here, sometimes making the game totally unbalanced. When I think that I'm having a good run, there's a freaking huge @ss wave, right beside my city that simply overwhelms my defenses. Very frustrating. Actually "having a good run" is already hard enough because some upgrades aren't as good as the others. And some are simply a necessity (gold, food and wood, basically). Talking about resources: food is by far the most essential resource. And yet on two seasons you suffer from a food shortage... Why? Also why all bosses hav…

Very elegant way to make a player involved with the stone tablets for quite a number of runs and then give him a reason to stop playing without big ending splash but just a message to soak in =) Bravo

Fun and addictive, not perfect but very fun and worth the money. As an aside. did have horrible frame rate but turning antialiasing or the narrator off fixed it.

Not worth 11 dollars, I enjoyed the demo and wanted more and regretted it. Skill issue on my part but there are better roguelites with more content for same price.
