Refence

Refence is Muurou Tech's idle defense roguelite, released on Steam on March 4th, 2025 for Windows, Mac and Linux, with an Android version alongside. The name is a portmanteau of roguelike and defence that the developer leaned into, and the design leans just as hard into the timeline-hopping structure: every run hires heroes to hold a castle against the Demon Realm, and every reset moves you to a fresh timeline with stronger baselines.

What the loop feels like

You hire heroes, set their traits against what the wave is actually fielding, and watch the defense hold or fold. The castle upgrade pays for itself, resources trickle, and the first timeline ends with a wall you cannot brute-force. That's Refence.

You hop to the next timeline, relics still equipped, research still done, and the same wall is now a speed bump. Deeper timelines reprice the problem, trait mismatches stall whole runs, and the quest system keeps the income moving while you plan. That's Refence.

How it actually works

The run layer is automated hero defense: hire, position and deploy heroes who fight the Demon Realm's waves on their own, with success hinging on matching hero traits to specific enemy types rather than stacking raw levels. The castle is the hub and the shell, with physical upgrades unlocking hero capacity and structural bonuses. Around the fighting sit three support systems: a research tree of permanent quality-of-life and combat unlocks, relic crafting for powerful gear that persists across timelines, and idle quests that dispatch heroes for resources while you are away.

The meta layer is where the roguelite half lives. Moving between timelines resets run-based metrics while carrying over crafted relic tiers and research, so each reset is a deliberate trade of progress now for multipliers later. The pacing anchor is that research tree, which gradually converts manual micromanagement into automation, and veteran advice converges on one theme: tailor the loadout to the timeline, because trait synergy beats levels every time.

Where it stumbles

The rough edges cluster in the interface. Community threads flag automation and bulk-upgrade buttons that behave unexpectedly, including one that consumes resources like paper without making it obvious, and hero balancing is uneven, with certain summoner synergies and utility scaling feeling undercooked next to the mainstream picks. The late game leans idle by design, which some players will correctly read as a waiting game with occasional tactical garnish. Set against genre giants, it is a compact number-cruncher rather than a deep systems sandbox, and it does not pretend to be one.

Playing it today

On Steam for Windows, Mac and Linux with achievements, cloud saves and leaderboards, and on Android for the couch version. Reception on Steam has been mostly positive. If the hero-as-tower structure works for you, Idle Tower Defense strips the idea to its skeleton, and Magic Research is the reference point for research-tree pacing done generously.

The verdict

A tidy timeline-hopping defense idler with real trait strategy at its core and a UI that occasionally fights back. Ride the timelines, read the tooltips twice, and let the relics do the remembering.
