✦ 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, all achievements take roughly 18 hours.

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.
