TitanStrike

Titan Strike** is a 3D runner + fighting mobile game. You control a giant running automatically along a road, collecting tiny humans to grow in size while dodging obstacles. At the end of each stage, you face off against enemies in an intense brawl, then launch them flying to earn diamond multipliers.

### Core Gameplay

The game has 30 stages. Each stage consists of two phases:

#### Phase 1: Running

- Auto-run: The giant runs forward automatically — no need to control speed or direction.
- Swipe to move: Swipe left or right to dodge obstacles and collect items.
- Collecting humans:
- Same-color humans → +1 size, +1 energy.
- Different-color humans → -1 size, -2 energy, skin turns gray.
- Size affects model scale (0.2x – 0.4x) and HP (size - 10).
- Color switching: Run through red/green/yellow glowing gates to switch to that color. Match your color to the humans you want to collect.
- Obstacles:
| Obstacle | Damage |
|----------|--------|
| Brick wall | Size -10 |
| Rotating blade | Size -25 |
| Rotating wall/ring | Size -25 |
| Moving gate | Size -25 |
| Spike platform | Size -25 |
| Spike road | Continuous damage |
- Energy & Invincibility:
- Reach 50 energy to trigger Invincibility Mode.
- While invincible: rainbow skin, all humans become same-color and auto-collect, speed increased by 1.5x.
- Energy drains 1 point per second; invincibility ends when energy hits zero.

#### Phase 2: Combat

Three battle types depending on the stage:

##### 1. Normal Fight (Normal Stages)

- Face off against an enemy, each with an HP bar.
- Tap rapidly to throw alternating left and right hooks.
- The enemy fights back periodically — watch your health!
- When enemy HP reaches zero, deliver a KICK finisher to send them flying.
- Flight distance determines your diamond multiplier.

##### 2. Boss Fight (Boss Stages)

Three sub-phases in a loop:

Dodge Phase: The boss attacks multiple times. Red circles appear on the ground as warning — swipe to jump between 4 positions to dodge.
Attack Phase: The boss becomes stunned after its attack. Tap rapidly to deal damage within the time limit. When time runs out, the boss rages and returns to dodge phase.
Finish Phase: Once the boss HP hits zero, it falls into a coma. Tap frantically within the countdown to maximize your multiplier, then deliver the KICK finisher.

##### 3. Chest Fight (Bonus Stages)

- A 5-second countdown to tap the screen as fast as you can.
- More taps → higher multiplier → more diamonds.
