  Patch 2.0.4 - Level Editor Fixes + Easy Discord Sharing

  If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Misc ChangesAdded a Discord Webhook that lets you post your Custom Level on Discord after publishing The "Share" button shows up after publish successReplaced the 2nd Event Level "Art Challenge: Siren" with "Fort Harvest"The Siren level feels too similar to the Turret Clam level, with the same kind of chaotic energy. This switch is to vary up the event more, and give you a more "normal"-feeling level that Darthen had spent a lot of effort on. ------------------------------------------------------------------- Bug FixesFixed a glitch where the game UI could confuse regular, semi-custom, and fully-custom level typesReported by alexniccah Fixed a glitch where the Anniversary Event notification does not go away after level completionReported by Virty Fixed a visual bug where invalid placement marks can remain on Level Editor objects if you erased multiple of them stacked on top of each other Reported by Rainbow3ntity Fixed a glitch where Custom Level ratings can only display as 5 stars or 0 stars Fixed Russian localization display issues

  2.0 Major Update - Anniversary Event & Level Editor!

  Operation Octo turns 1 year old today! To celebrate, we are launching the 2.0 Major Update - Introducing the Level Editor! Create insane shenanigans and share them with your friends on the OO Steam Workshop! There are already lots of ultra-creative levels created by our beta testers over the past week. An anniversary event is going live, where you get to explore several of the custom levels :) Level Editor is unlocked after Level 2-10 "Sergeant's Plateau"(If you have trouble downloading levels, right click on the game in your Steam library, Properties > Installed Files > Verify Integrity of Game Files)Promo art by Matthew Ramirez (You've probably seen Matthew's work before - He's the guy that makes thumbnails for Chris & Jack 😉) ------------------------------------------------------------------- Tune in next week for the OO Anniversary Part 2, an early access to the Volcanic Ridge turret "Whale Artillery"... If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesFrosty Pistol Shrimp attack range increased from 7 to 8.5Frosty Shrimp is one of the worst Frosty upgrades there is, with its low cost being its only advantage, which is simply not worth spending a precious Elixir on. I had considered letting Frosty Shrimp always target the closest enemy instead, but I did want Shrimp to remain as the strictly-single-target slowing option. The range increase will hopefully compensate for Shrimp projectile's slow travel, so that it manages to slow down a target sooner during its approach. More importantly, upgrading a Shrimp into Frosty will now allow you to target a cannon that is shooting at your Mussel, which could seriously change up the early-game dynamics. This is also part of the recent design philosophy shift, where Frosty turrets gain additional utility aside from slowing. ------------------------------------------------------------------- Bug FixesFixed a glitch...

  Patch 1.6.3 - Fixed Leviathan Battery Glitch

  I said last night's patch was gonna be the last one before the 2.0 update. Of course another new (and totally game-breaking) bug got discovered 😬 I'm not gonna say this will be the last patch before the major update, so I don't jynx it 😏 If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Bug FixesFixed a glitch where Leviathan Battery cannot be picked up by OdinReported by Studimus ------------------------------------------------------------------- Misc ChangesAdded Spanish, Romanian, Czech, Russian localizations for the April Fools eventI kept Everywhere Siren a secret even to the translators. The translators immediately labored away at the new texts after the update dropped, and how did I repay them? I forgot to download their translations before making the last patch! SooorrrryyyyyyyyI was gonna let their efforts go to waste too (I was in the middle of some super hardcore asset migrations for OO 2.0), if a game breaking bug wasn't found that necessitated this emergency patch 🥲

  Patch 1.6.2 - Custom Level Issue Fixes

  More bugs surfaced surrounding custom levels - This should be the last round of bug fixes before the 2.0 major update (for the Level Editor) in a month! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesWhile chasing a bandanaed / charmed skeleton, Spiky Urchin now tries to pathfind to the tile ahead of the enemyThis allows Urchin more time to stay still & attack a banded skele, before the skele walks out of range and forces the Urchin to start rolling again in pursuit. ------------------------------------------------------------------- Bug FixesFix attempt for a glitch where custom levels sometimes fail to generate Level Boundaries if it is the first level scene you entered after game launchReported by BullsiFixed a glitch where insta-turret achievements that require trackers, such as Axe-A-Lot-O, can fail to unlock inside the GraveyardSpecial thanks to Rainbow3ntity for running a debug build to help me diagnose the issueFixed a glitch where selling an upgraded Graveyard turret could give you back 2 elixirs upon switching regionsReported by EndermanonymousFixed a glitch where Zappy Jelly could fail to clear some acid tiles & light up the entire mapReported by TylazerMKGame crash on launch fix for computers without dedicated GPU's / with low VRAM Reported by TheStimerGamesThis is a temporary, less thorough fix - I intend to VERY significantly optimize the game's performance on the memory front during the upcoming major update's beta phase (in case things go majorly wrong, the beta period will catch the issues). Fixed a glitch where skeletons are stuck in place when spawned for the first time during a Graveyard simulationFixed a glitch where a pearl could instantly snap to a Watchdog's mouth if said pearl had moved since Watchdog began his pickup animation Fixed a glitch where Spiky Urchin continues sliding along a path if it dies while rolling
