Ukrainian Localization

Operation Octo has been translated into Ukrainian by Lavauk!
Pretty good timing - Matches the new Argonaut's color scheme ;)

If you encounter any bugs while playing, please report them to me on Discord! -------------------------------------------------------------------

Balance Changes

  • Inside Level 2-5 "Clam Farm", only pearls that were initially produced by the player (before getting consumed by Argonaut) will count towards the pearl production goal after the Argonaut refunds those pearls

  • This is to prevent Argonaut spam from becoming the ultimate Clam Farm speedrun strat; Note that due to coding limitations, new Argonauts spawned by Mutant Argonaut will not remember if their stored pearls were produced by the player.

  • Frosty Sniper Turtle now has passive regen

  • This is to further incentivize using Frosty Turtle as a frontline tank, differentiate this upgrade from the other Frosty upgrades, and offer additional benefits to having one more of this single-target slow-er.


-------------------------------------------------------------------

Bug Fixes

  • Fixed a glitch where Argonaut could gain additional stored pearls when upgraded

  • We fixed this bug live during a Discord stream ;) Upgraded Argonauts had been secretly producing extra pearls - They'll feel a bit less insane now after the fix.

  • While a turret ball is tossed in mid-air inside a Graveyard, you can no longer exit the region or start simulation

  • While selling a turret inside a Graveyard, you can no longer exit the region

  • This prevents the turret you're about to place down from going missing if you left prematurely, since the turret's placement doesn't get saved until it is truly deployed.

  • Fixed a glitch where the Frogfish card drop after Level 2-4 is shown as a turret card instead of a gadget


-------------------------------------------------------------------

Misc Changes

  • Fixed Hollow Argonaut's manual entry, which erroneously displayed its "Damage" as "Heavy"

  • Hollow Argonaut's manual entry now displays "Ghostly" trait

  • Reported by TylazerMK
