- v0.3.0 — Erosion - 17 September 2026
This patch overhauls the difficulty system. Easy and Normal are now Stable and Balanced, and Hard has been broken apart into Erosion — a new 10-tier ladder that goes much further than Hard ever did, with each tier adding one more twist on top of the last. If you already cleared Hard, Erosion 2 is waiting for you right away. Good luck out there.New ContentDifficulty system overhaulEasy → Stable, Normal → BalancedHard → Erosion, a new 10-tier difficulty.

- Coming Next Week — Erosion - 10 September 2026
No patch this week — we're taking the week off to focus on what's coming next. Instead, here's a preview of the update landing next week.ErosionErosion is the new tiered challenge system that replaces the Hard difficulty. Instead of a single "Hard" toggle, difficulty is split into tiers, and each tier stacks a new constraint on top of the previous one — leaner shops, tougher enemies, pricier potions, angrier Guardians, and more. Higher tiers reach well beyond the current Hard, for players who want a run that pushes back harder.As mentioned last time, part of Erosion is a set of terrain hazards themed to each stage — damaging floor patterns that force you to keep moving and read the arena, not just the enemies.At the highest tiers, every Guardian also gains a brand-new attack pattern of its own. Even if you know every Guardian inside out, Erosion will have something new waiting for you.S…
- v0.2.7 — Altar & Boss Soul Balance - 3 September 2026
This patch is a light balance pass centered on the Altar, giving a boost to rewards and Guardian Souls whose effects were too weak to be worth choosing, along with a small reach increase for Frostwind.Something bigger is also in the works: the Hard difficulty is being broken into several tiers — not just a finer split of what exists now, but new tiers beyond it for players who want a harder run — and part of that is a set of terrain hazards themed to each stage. More details in a future patch.BalanceAltar: Twin Growth → Full BloomRenamed, and reworked from "two random skills gain 1 level" to "all of your skills gain 1 level"Altar: Full BlessingIn addition to fully restoring HP, now also increases Max HP by 50Altar: Pact of BloodCurrent HP cost: 100–300 → 50–250Max HP gain changed from half the HP spent to the full amount spentAltar: TransmutationThe transformed skill is now taken to max…
- v0.2.6 — Chill Trace Rework & Skill Balance - 27 August 2026
This patch centers on a full rework of Chill Trace and a broad pass over skills that were falling behind. Chill Trace is no longer just a small slow on hit — landing active-skill damage now builds chill stacks, and a full stack detonates for burst damage and a stun. On top of that, a handful of skills got faster cooldowns, more damage, or bigger hitboxes. There's also a change to how Guardians handle slows: crowd control resistance now weakens the slow instead of blocking it outright. Have fun freezing things solid!BalanceSkill: Chill Trace (Reworked)Slow duration: 2s → 5s, and now refreshes every time you deal magic damageDealing damage with an active skill now adds 1 chill stack (max once per cast); each stack adds an extra -10% movement speedAt 4 stacks, the stacks are consumed to deal 100/140/180/220/260/300 magic damage and stun for 1.5sBecause the slow now scales by strength rathe…
- v0.2.5 — Steam Input Stability & Gamepad Navigation - 20 August 2026
A follow-up to last patch's gamepad support: this one is all about ironing out the wrinkles. Steam Input should now behave correctly when a controller connects mid-session, targeting feels more precise, and menu/battle navigation is smoother in several spots. A few bug fixes on top. Thanks for all the controller feedback so far!BalanceGold SlimeNow starts its escape countdown automatically after a delay even if never detected by the playerImprovementsGamepad TargetingSimplified on-screen target detection and tuned the aim cone for more consistent target selectionGamepad NavigationStore focus now moves more naturally overallImproved focus handling when skills are dismantledAdded a pulsing highlight to buttons that were hard to notice while focused with a controllerAchievementsScroll position now resets to the top each time the achievement list or unlock popup is reopenedBug FixesTooltips…
- v0.2.4 — Gamepad Support - 13 August 2026
The big one this time: full gamepad support. Every screen — title, battle, selection windows, popups, results — now works end to end with a controller, including rebindable inputs and on-screen icons. On top of that, a few balance changes to Guardian Random Skills and the Staff weapon, plus a couple of bug fixes. Grab a controller and give it a try!New FeaturesGamepad SupportFull controller support across the title screen, battle scene, and all selection/popup/result windowsAdded rebindable gamepad controls and on-screen button iconsBalanceGuardian Random Skills: Seal of Dominion / Seal of Chaos / Seal of RestraintChanged from sealing nearby targets to sealing all enemies for a durationWeapon: Staff — Arcane SurgeFixed Arcane Surge triggering non-magic skills instead of magic skills onlyBug FixesSkillsFixed Chain Lightning hitting a single target twice

- v0.2.2 — Enchant Fix Follow-up - 4 August 2026
A quick follow-up to v0.2.1 — the previous Enchant fix missed the root cause. The next-level offer generated in the Store and Skill Packs never carried the Enchant over, so in practice almost every level-up of an Enchanted skill stripped it. Should be fully resolved now.Bug FixesSkillsFixed Enchants being lost when leveling up via the Store or a Skill Pack, which affected most level-ups
- v0.2.1 — Cursor Confinement and Bug Fixes - 4 August 2026

- v0.2.0 — Goddess's Blessing - 30 July 2026

- v0.1.5 — Boss Attack Tell and Bug Fixes - 23 July 2026

- v0.1.4 — Save & Quit and Bug Fixes - 16 July 2026
We've received requests for a way to save mid-run and continue later, so this update adds exactly that. To keep the tension intact, a save can only be loaded once and cannot be made during battle.So next time something comes up — feel free to step away for a bit!New FeaturesAdded mid-run savingUse "Save and Quit" in the pause menu to save your adventure, then resume it with "Continue" on the title screen.Cannot be used during battle.ImprovementsHovering over the wave timer now shows an explanation of how waves and bonus rewards workAdjusted the pause menu positionBug FixesFixed visible seams in the tilemap and HP bar
