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!

addedBalance ChangesFrogfish 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.

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)!

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
