What's new

Update 1.0.0.4 is now available!

2025-10-21

Hello everyone! I've been working hard on a big content update for "Kill a Million Rats", and it's finally live! Here's a list of the major changes: New Combat Progression Instead of obtaining a single combat upgrade at the start of each wave, you now collect experience orbs (in classic survivor-style) from dead rats. The total number of upgrades over a single run has been increased due to this, so I've added a bunch of smaller repeatable upgrades too! Boss Behavior Overhaul Giant Rats no longer have automatic invulnerability windows at HP thresholds! All their attacks have also now been reworked to encompass a wider variety of special attacks. Fighting these guys should now feel much more challenging but fair. Villager Buff Villagers have been buffed to be much sturdier, and can take a lot more damage before going down. Village Bell HP Bar

Read the full notes

I've added a HP bar for the Village Bell in the upper right corner, so it should be easier to determine how much damage it's taken. Putting it together with your own HP/Hearts makes it easier to tell your current position at a glance. Let me know in the comments if you enjoyed this free content update, or if you have any suggestions for future improvements! Lots of love, -nerdook

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...

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.

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...
