About This Game

Flux Tower Defense

Stop every wave, or lose the run. Enemies erupt from the red portal. Your fortress — teal, glowing, alive — is the only thing between the map and extinction. One death wipes your save, so every tower placement counts.

Elemental attributes, layered deep

Every tower levels from 1 → 15 with branching milestones:

• Lv 5 rolls a random element: LAVA (burn DoT), GLACIER (slow), ELECTRIC (chain), or STEEL (crit).
• Lv 10 upgrades that element to Tier 2 — a unique ability. LAVA burns hits for 25% dmg/s over 3s. GLACIER has a 20% chance to freeze. ELECTRIC jumps to nearby enemies. STEEL lands 2× crits.
• Lv 15 rolls a second attribute, stacking two elements on one tower. The combos run deep.

Place. Sell. Reshape.

Towers block the path. Traps walk over. A* pathfinding recomputes the instant you sell, so mid-wave repositioning is a real tactic — kite elites into your choke, open a shortcut, swap a Lv 10 into a Lv 1 at the front line when the money calls.

Endless waves, boss rotation

Wave 1 is a tutorial of Slimes. Wave 2+ drops a boss variant of a random species at the end of every spawn queue — 5–10× HP, larger, meaner. 13+ enemy types each have dedicated mechanics you'll learn the hard way.

Live tools: damage meter + enemy bestiary

• Damage Meter — click the Σ icon to see which tower is carrying your run.
• Enemy Bestiary — locked until first sighting, each entry explains the mechanic.
• Game-over summary — survived time, kills, top damage dealers, attributes rolled, and a Personal Best badge on a new high wave.

Steam integration

• Steam Cloud — saves, progress counters, and settings sync across all your devices.
• Steam Rich Presence localized in 14 languages.
• Steam Timeline — every wave clear and death lands as a clip-worthy moment.

Built-in accessibility

• Color Blind Assist — attribute glyphs + text labels on every tower so color alone is never load-bearing.
• Reduce Motion — calms portal rotation, fortress pulse, damage shake, and UI glow animations.
• Mouse-only play — pause button on the HUD, every action reachable without the keyboard.
• Independent volume controls for music and SFX, with a global mute.

Aesthetic — zero image assets

Every enemy, tower, effect, and UI element is rendered in pure Canvas 2D. Portal triangles rotate. Fortress shields peel off as life drops. Wall towers auto-tile into crenellated battlements. Lv 15 dual-attribute towers shimmer with two elemental colors. No PNG sprite sheets. No pre-rendered tiles. Just code painting pixels every frame.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Flux Tower Defense uses generative AI in the following development areas:

• Store page artwork: Main, header, library, small, and vertical capsule images, library hero, library header, and page background were created using AI image generation tools with human direction, prompt iteration, and post-processing. The "FLUX TOWER DEFENSE" wordmark typography was added manually.

• Achievement icons: The 20 in-game achievement icons were generated with AI image tools using hand-authored prompts and manually curated selections.

• Localization: Non-English store page descriptions were translated with AI assistance and reviewed before publication.

The game's runtime contains NO generative AI. All gameplay systems (towers, enemies, traps, waves, pathfinding, damage, upgrades), UI, and in-game visuals are deterministic code rendered live via HTML5 Canvas 2D. There are no pre-rendered sprites, no AI-generated game content, and no AI inference during play.
