About

Lily Quest

Features
Read full description

Lily Quest is a cozy backpack RPG and roguelike auto battler you can play offline. Fit items into a grid backpack, merge them into stronger gear, and watch the battle play out by itself. The Moon Lily has vanished from the pond — and without its light the water will freeze. Little Pip the frog grabs Grandpa's old backpack and sets off to bring it back. • EVERY SQUARE COUNTS Swords, shields, potions, mushrooms, magic crystals: every item has its own shape and fires on its own timer. Turn pieces to make them fit and mind the neighbours. A whetstone next to a sword sharpens it, a banner beside your weapons speeds them up, a sunflower among your plants makes them grow. Inventory management, the cozy way. • MERGE ITEMS, DISCOVER RECIPES Drop an item onto its twin to level it up, all the way to level 3. Lay the right pair side by side and after the battle they fuse into something new. There are 15 recipes to find: can you fill the whole book? • NO LUCK IN BATTLE Like in any auto battler, the fight runs on its own, but there are no dice rolls: the same backpack always fights the same way, so every win comes from your strategy. Speed battles up or skip straight to the result. • FOUR HEROES, FOUR WAYS TO PLAY Pip the brave knight, grumpy Grandma Maud the alchemist, calm Moss the druid and hyperactive Zip the ninja. Blades and shields, poison and potions, growing plants, lightning-fast strikes: pick your style. • A ROGUELIKE STORY ADVENTURE Six chapters from the Reed Shore to the Heron's Tower, each a fresh run that starts with just a few items. Choose your path on the map, visit merchants, meet strange travellers, rest by the campfire and face a boss at the end of every road. Finish the story to unlock Heroic mode, and replay chapters for three stars. And the Heron is not quite who she seems… • THE GREAT POND TOURNAMENT Climb the ranks against rival travellers, earn trophies and chests, and fight for promotion in the weekly league. Every rival is generated inside the game, so the tournament works offline too. • OFFLINE AND ONE-HANDED No internet needed. Portrait mode, big clear items, short battles. Every step is saved: close the game anytime and pick up where you left off. Fully translated into English, Español, Português, Deutsch, Français and Русский. • Daily gifts, camp upgrades, hero levels, perks and new looks for every hero. Lily Quest is free to play and shows ads. All rewarded videos are optional.
