Think of the Steam soundtrack as a tip jar for me, if you liked the game :)

New Music for Special Game Modes

Daniel Teles has composed some (insanely good) new tracks for Mini-Game Levels & Ultimate Battles (Turret Clam Levels)!

I gave Daniel the "Crimson Front soundtrack" as reference for the Ultimate Battle, hence the track has the "jazz swing big band vibe" - Go check it out inside the game or the OST now!

New Turret - Argonaut

Welcome the most complex / unique attacking turret yet - The Argonaut! (i.e. Paper Nautilus)

Argonaut occasionally consumes a nearby Pearl to enhance its attack range - It has 3 forms depending on how far upgraded it is!
After a while, the Argonaut self-destructs and gives ALL the Pearls back!

Argonaut is an incredibly powerful yet unreliable attacker (due to its temporary nature) - How good it gets depends on how many Pearls you manage to feed it!

Argonaut fits well into both cycle decks (free full refunds = free cycle!) AND heavy decks (acing at early-game while allowing you to fully transition into expensive attackers using the refunded pearls).

Unlock Argonaut now inside the Sandy Shallows store (Bought for 2 Rubies after you've beaten Level 1-10)!

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

Balance Changes

Frogfish profit amount reduced by 5 Pearls

Frogfish has been almost universally thought of as OP since his recent debute. Making a small profit every 20 seconds really adds up over the course of a level, especially when a player intentionally leaves Large Pearls around to be collected by Frogfish. In addition to making Frogfish less of a risk-free & superior Pearl Tree, this nerf essentially degrades the Pearl that a Frogfish produces, so that it's much harder to feed Large Pearls that were spitted out by a previous Frogfish right back into a new Frogfish for more profits.

A knocked-out turret can no longer give souls to multiple soul collectors (e.g. Hollow Deathray)
Hollow Deathray is now only able to collect souls from knocked-out turrets within his attack range

Soul-collection has been reworked in preparation to it becoming a more common Hollow turret gimmick, where multiple soul collectors will have to share the limited number of turret K.O.s on the field.
Potion Factory now caps his current HP whenever he launches a potion; The HP cap decreases exponentially after each potion launch

This will not impact your interactions with Potion Factory if you're attacking him as you should. However, a neglected Factory will now generate weaker and weaker shields as time goes on, to the point that he dies after the 7th Potion launch. When improperly addressed, a Potion Factory will still mess you up, but he will no longer remain a perpetual threat to players who ignore Factories completely.
Tangler Skeleton's tentacles now automatically retract after 40 seconds
Tangler Skeleton ability minimum reload time increased from 6 seconds to 10 seconds

I had wanted Tangler tentacles to be a persistent chore you must address sooner or later, and to have illumination play a bigger role when countering Tangler, since tangled turrets that remain unseen could secretly sabotage you for the entire level. However, given how overwhelming & annoying people already find Tangler to be, I'm now allowing undetected tentacles to eventually disappear. A turret being shut down for 40 whole seconds already accomplishes Tangler's role of supporting her current wave. Plus, low-profile, outside-the-base turrets such as Pleco & Starfish are now more desireable picks even when Tangler is present - Even if you can't go out of your way to free them, they'll now break free eventually. (This also reduces cases where a player thinks his Starfish is in position to counter Potion Factories, but ends up dying horrendously to potions because said Starfish had been tangled the whole time.)

While Odin is disoriented and stunned at the same time, if an incoming damage would reduce the disorientation timer low enough, clear the disorientation effect immediately
If Odin recovers from disorientation while stunned, Odin now gains an extended disorientation immunity period, starting from when stun wears off

More reworks to make recovering from Disorientation less disorientating. Will add some super noticeable visuals for Disorientation recovery next update too...

Potion Factory now resets his deployment / reload time when stunned
Reaper Skeleton now resets his strike cooldown if stunned while patrolling

For consistency with other stun resets, and to provide additional benefit to players who cycle Zappy Jelly onto skeletons camping outside of the base

Bug Fixes

Fixed a glitch where from certain positions, a Frogfish could stretch its tongue across a mountain tile to reach a Pearl inside a Clam

Reported by IdiotWithATophat

Fixed a glitch where Odin' regen rate could be slowed down when FPS is extremely high
Fixed a glitch where Spiky Urchin would not move towards stationary enemies that occupy tiles
