Welcome, everyone joining from Steam Next Fest! This update polishes battle and your first 10 minutes with Sia. ⚔ Battle is much quieter. In the first 10 minutes, speech bubbles went from 126 to 34. Regular floors now show a floating "▶ 12" instead of a line, and Sia comments on kills far less often. The first 🔷 skill point tip was instantly covered by other lines and never seen. New records, new areas and boss rules now come together in one bubble. ⏩ Auto Advance trial: for your first 15 floors, Sia moves on to the next floor by herself, even without the skill (she stops before bosses). Before, if you didn't touch anything, she stayed on floor 1 the whole time. At floor 15, learn 「Auto Advance」 for 🔷5 to keep going. Time with the app open but battle turned off now earns a little gold when you turn battle back on (after 30+ minutes — half of what you'd get with the app closed). Right-click menu: ⚔ Battle — start it without opening Home. Upgrade rows show "+N/Lv" with your multipliers included, and locked rows say "Opens at ₩N". The boss timer prediction could show green and you'd still lose — it now leaves a safety margin. Support alerts and gift lines no longer interrupt battle (you still get the rewards). Fixed: closing the app after beating a boss but before pressing "Next" brought the same boss back — with its rewards again. Beating a boss now moves you on right away. Changed: Bond 💞 from floors and bosses now comes only the first time you reach a floor. After a Rebirth, climbing the same floors again was giving it again — about ten times more than intended. {STEAM_CLAN_IMAGE}/46254569/d176cea82ba787ed23bbff744ff61b3f085d6cd0.gif 👋 The tutorial said five head pats reach Bond Lv.1 — it actually fell a little short, and the sixth pat got you bitten. It now says "five pats and one 🍖 treat", and after the fifth pat Sia shows you where to feed her. Alerts and chatter no longer cut into the first-meeting scene, and greetings, letters, requests and the weather location...
⚔ Battle has no end now. Past floor 4300, monsters stopped getting stronger, and from around floor 4500 battle could freeze. Numbers now keep growing as high as you can climb. Fixed: lag in battle around floor 4000. Battle skill window: maxed skills fold into one row, so the window no longer stretches to the bottom of the screen. Buttons respond reliably, and closing the window no longer leaves hidden copies running in the background. The rebirth hint in the shop showed the attack multiplier as a very long number. It now reads like ×2.61T. {STEAM_CLAN_IMAGE}/46254569/d176cea82ba787ed23bbff744ff61b3f085d6cd0.gif Fixed: the line Sia draws when she stares at you came out of her forehead. It now starts at her eyes. Mac: fixed the screen freezing for a moment while Sia charged up to crack the screen. Throwing a paper plane made a sharp beep — it's a light whoosh now. The petting sound is softer, too. The title of the error window shown when an image fails to load is now translated.
