Fusiomon is my indie passion project. With AI and gpt-image-1, a childhood dream of freely fusing Pokémon became real. On Oct 23, the model is scheduled to shut down, putting Fusiomon's visual identity at risk. @OpenAI, please offer paid legacy access. #KeepGPTImage1

DRAG & DROP MONSTER PLACEMENT

Monsters can now be dragged directly from the deck onto the hex grid island.
Placement is supported by a color-matching particle effect based on the monster image, creating a clean spawn moment.

LANE PREVIEW ON PLACEMENT

While placing a monster, the game now highlights its six possible attack directions in real time.
All tiles along those lanes stay visible, while everything else is dimmed out.

ALWAYS-VISIBLE DECK

The deck is now always accessible directly in the main view via a scrollable side panel.

All monsters and their key stats are visible at a glance, removing the need for separate menus.

ISLAND ELEMENT ICONS

Elemental edge tiles now reveal their elements through clear icon overlays.
On interaction, each tile shows exactly which elements are present, making the underlying mechanics readable at a glance.

SMOOTH CAMERA & TILE FOCUS

Built a camera controller that supports smooth zooming and panning across the island.
When zooming out, the view recenters automatically, keeping the whole island readable on both desktop and mobile.

SNAKE BOBBING EFFECT

I added a new snake-like bobbing animation to bring more life into the island view.
The tiles now move in a smooth wave from front to back and back again, which makes the whole board feel much less static.

PROCEDURAL ISLAND GENERATION

Every island in Fusiomon is generated from a unique seed.
A stable core of inner tiles is surrounded by a ring of elemental tiles, defining both layout and resource distribution.
To expand, players must clear edge mines.

HEX TILE FOUNDATION

These tiles are the core building blocks of every island in Fusiomon.
Core tiles are simple hex meshes with a 2D shape, using shading and front-face depth to create a clean pseudo-3D look for monster placement.

MONSTER MASTERY & XP PROGRESSION

Monsters can now gain XP through battles and level up their Mastery Level.

Each mastery level grants a Bronze Badge, which feeds directly into the tiered badge system.

MASTERY BADGES & TIER PROGRESSION

Every monster level-up now grants a Bronze Mastery Badge.
From there, progression is fully generalized: two Bronze become Silver, two Silver become Gold, then Platinum and beyond.

20 ELEMENTS IN FUSIOMON

The elemental roster is now complete with 20 unique elements, each with its own color identity and combat role.

The newest additions expand the system further and tie into a growing network of strengths and weaknesses.

#indiedev #gamedev #fusiomon

[Fusiomon @FusiomonTCG]

NEW ELEMENT: SLIME

Slime adds a defensive, adaptive twist to combat.
With Assimilation, the weakest element of an incoming enemy projectile is negated and converted into healing instead of damage.

#indiedev #gamedev #fusiomon

NEW ELEMENT: HOLY

Holy introduces a strong counterplay element to debuff-heavy strategies.
Its Purification ability removes all weakening effects from the monster and all adjacent allies, restoring 50% of their current HP for each removed debuff.

NEW ELEMENT: CRYSTAL

Crystal is a new element built around positioning and synergy.
With its Bundling ability, a fired projectile gains additional Crystal power based on all adjacent monsters, rewarding tight formations on the hex grid.

NEW ELEMENT: METAL

Metal joins Fusiomon as a new combat-focused element.
Its signature ability, Piercing, allows attacks to hit not just the target, but all monsters lined up behind it on the hex grid.

NEW CARD PACKS

The card pack lineup just got expanded.
Alongside the existing packs, two new ones joined the pool: Ruby and the special Aurora pack.

Starting the year with a big rework of Fusiomon.

Hex-based island expansion, elemental mines, deeper monster stats and progression.
A lot is still work in progress, but the core direction finally feels right.

Small sneak peek of what I’m building next.

For those who code after.

Clair Obscur: Expedition 33 helped me refocus. Seeing what the team behind the game (@expedition33) created was a reminder of what’s possible when you fully commit to an idea.

A small tribute.

The Fusiomon Beta chapter has ended.
I’ve started rebuilding the game around a new Hex-Grid world giving fusion a real purpose.
