About this game
Swim. Grow. Try again.
Siegeturtle is a cozy idle roguelite auto-battler about a turtle making its way home through hostile seas. Your turtle moves automatically while companions support you along the journey. Upgrade attributes, skills, and equipment to push a little further with every run.
A jetpack? A cannon? Why not both! Blast through diverse biomes with quirky upgrades and unexpected power-ups.
Unlock Companions!
Recruit dolphins, unicorns, seals and more! Each grants a unique ability to your party.
Fish for Power
Send your turtle out to fish between battles. Sell your catch for gold, or keep them for passive stat bonuses. Upgrade your imaginary fishing rod to reel in even rarer finds.
Level up your favorite attributes!
Strength, Agility, Intelligence, or Vitality. Which will you choose? Each attribute shapes your turtle in unique ways, letting you grow stronger with every run.
Customize your playstyle. Spend skill points to upgrade your turtle and companions, unlocking abilities that match how you like to play.
Hunt for legendary loot. Summon powerful bosses to earn new gear and discover synergies that boost gold gain, regeneration, drop rates, critical hits, and more. Break down unwanted equipment into upgrade materials to raise your summoning level and increase your chances of scoring rare items.
Ascend and Evolve
When the time is right, reset your journey in a surge of new power. Each ascension grants permanent upgrades to make your turtle faster and stronger than before!

v1.2.1 - Space Octopus + Dreamsand Upgrade!
v1.2.1 is released!Space OctopusA new ascension upgrade has been added. There was an upgrade that allows you to catch extra fish, but I received feedback that some people find the pearl catches more valuable, and extra fish catches not triggering the pearl catches was not optimal.Thus I have added a new upgrade that improves inventory slots, to allow more longer idle playstyles, increased auto-sell speed, but also allowing extra fish chance to trigger pearl catches!Final Dreamer upgradeI also read feedback regarding the Dreamsand upgrade to persist dreamsand, and I've decided to improve that as well!Thus, you may now upgrade 'Dreamer' all the way to Level 12, a newly added level that lets dreamsand persistence go up to 100%, so that there is no loss at all in the late-game.Auto Enhance minor improvementsAuto-Enhance was meant to be a new unlock granted as an idea for a distant 'T Update'. But since it will take time, I've temporarily made auto-enhance now unlock after 10 ascensions, which is much earlier than designed but should help smooth out progression.Changelog:Add new ascension upgrade: Space OctopusAdd Level 12 Dreamsand, which carries over 100% dreamsandAuto-enhance now unlocks after 10 ascensions-YYZhttps://yyzstudio.com/discordRead full article on Community Announcements (YYZ Studio)Patch NotesOfficial

v1.1.30
v1.1.30 is released!I improved the speed breakdown tooltip as it has caused confusion regarding how speed is calculated.In the next update I will also add a tooltip to jetpack speed as it was thought to not tally, but it was actually higher than the jetpack passive if you have the Boot equipment. This will reflect in the next update:Finally, the 40th companion is not released, but the milestone requires 40 companions - I have changed the current milestone to require 39 instead of 40 as it is not possible to attain currently to address this issue.Changelog:Speed breakdown now separates additive and multiplicative bonusesFinal companion milestone requires 39 instead of 40 companions-YYZhttps://yyzstudio.com/discordRead full article on Community Announcements (YYZ Studio)Patch NotesOfficial
