Cataclismo

Digital Sun made its name with Moonlighter, a shopkeeper-by-day, dungeon-crawler-by-night hybrid that took two familiar genres and found something genuinely new to say by combining them. Cataclismo, released in full on Steam on 20 March 2025 after a period in Early Access, does the same trick with city-building, real-time strategy and tower defense -- and lands, on the evidence of 2,252 reviews sitting at 89.3% positive, mostly successfully, with one specific and recurring caveat about how far its central idea actually goes.

Height is strength -- a genuinely fresh building puzzle

The rule that makes Cataclismo click is stated almost as simply as a rule for chess: a block's structural strength scales with how tall the structure beneath it is. That single constraint turns fortress-building from a resource-spending checklist into a real engineering puzzle -- tall, narrow towers are strong but vulnerable and expensive; wide, sprawling bases are cheap but weak. "This game builds on an inspired idea that has RTS fans asking, 'Why hasn't anyone thought of this before?'" reads one review, echoed across the sample by reviewers who say they haven't encountered this specific mechanic done well elsewhere. Recent reviews lean into just how absorbing the building half can become on its own terms: "I spent so much time just building the castles that I forgot there was a wave coming," reads one; "sometimes I paused the game to just enjoy designing the weirdest castle I could," reads another, describing a creative freedom several reviewers say rivals dedicated city-builders despite Cataclismo's combat-focused framing.

A dark fantasy story that lands harder than expected

Wrapped around that mechanic is a story about Lady Iris holding back an encroaching, monstrous Mist, told with art direction reviewers consistently single out as a highlight independent of their feelings on the gameplay systems. "Great game with remarkable artistic direction!" reads one recent review; "the storyline and atmosphere is 10/10," reads another, from a reviewer who says they aren't usually drawn to brick-based builders. A handful of reviewers describe genuine emotional investment by the campaign's end, an unusual outcome for a genre that more often treats narrative as scaffolding for the mechanics.

Where the depth runs out, according to a real minority

Set against that is a specific, recurring account from reviewers who put real time in and came away less satisfied -- and it's worth taking seriously precisely because it comes from engaged players rather than bounced first impressions. "The issues I have with the game is about the lack of variety and depth," reads one review at over 55 hours logged, noting the flaws "don't really show before you played around 15-20 hours or so." Combat strategy is the most specific target: "there is no real strategy to utilize here," reads one review, "each time you play it's just 'build tall base and stick archers on top.'" Economy management draws its own specific complaints -- "please let me fix your game for you in two incredibly easy steps," reads one detailed review, "make oxygen not require stairs, make roofs braindead easy," describing friction in systems that should support the building fantasy rather than fight it. A recent review echoes the same frustration in gentler terms: "sometimes frustrating with how walls are placed and terrain needs to be destroyed before building properly, but friction does make sparks" -- a fair-minded framing that still names a real, unresolved rough edge.

A specific and unusual complaint from a very recent review concerns localisation: "the voice actors speak in English, but anything related to the lore is in Spanish(?) and pronounced in such a profound different way than English," a jarring inconsistency for a reviewer otherwise engaged enough to notice it. It's a minor point relative to the structural complaints above, but a concrete, checkable one.

Several of the more detailed negative reviews date from the Early Access period and specifically note that Digital Sun, while consistently responsive to feedback in conversation, didn't substantially change the systems those reviewers flagged before the 1.0 release. That's worth weighing against the achievement data, which shows a fairly normal difficulty curve for the genre -- strong completion on early campaign milestones (around 79% reach the first checkpoint) falling to well under 1% for the hardest Nightmare-difficulty clears, a shape consistent with a game whose early hours land for nearly everyone and whose hardest challenges are, by design or by tuning gap, reserved for a small dedicated core.

Verdict

7.5 out of 10. Cataclismo succeeds at the thing that's hardest for a genre-mashup to pull off: its central idea -- that height, not just resource spend, determines a fortress's strength -- is genuinely novel, well-realised, and wrapped in dark fantasy presentation strong enough to carry real emotional weight by the campaign's end. The complaints that keep it from scoring higher here are specific rather than vague: a real minority of committed players report the building and combat systems plateauing well before the campaign does, and some economy-management friction that reviewers across both the Early Access and 1.0 periods flag as unresolved. For most players, on the evidence of the review sample, the first fifteen hours alone justify the price -- just don't expect the puzzle to keep opening up indefinitely after that.
