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.

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.
