# Tetra Tactics
|
|
|
|
## Summary
|
|
|
|
Tetra Tactics is a strategic roguelike tower-defense.
|
|
The player defends their position by building modular structures (tetraminos) and
|
|
**exploiting their sinergies** while waves of enemies fall from above.
|
|
|
|
## Experience
|
|
|
|
**Primary Feeling**: The satisfaction of strategic planning combined with the
|
|
thrill of narrowly avoiding disaster ("just barely made it"). The player should
|
|
feel **clever** and **resourceful**.
|
|
|
|
A single encounter has a duration of ~10 minutes, or in general a short duration.
|
|
|
|
Depth emerges from the interaction between shape, positioning, timing, and build
|
|
choices.
|
|
|
|
## Inspiration
|
|
|
|
- Ball Pit
|
|
- 9 Kings
|
|
- Drop Duchy
|
|
- The King Is Watching
|
|
- Vampire Survivor
|
|
|
|
## Design Pillars
|
|
|
|
- **Exploiting Sinergies**: breaking the game is fun
|
|
- **Modular Depth**: simple tetromino rules combine in unexpected ways;
|
|
complexity emerges naturally from interaction
|
|
- **Consequence & Clarity**: threats are telegraphed clearly; every placement
|
|
has visible impact; failure is immediate and understandable
|
|
- **Momentum & Escalation**: each successful wave grows your toolkit and unlocks
|
|
new synergies; pressure mounts steadily without overwhelming
|
|
|
|
## Encounter Loop
|
|
|
|
1. **Telegraph**: Warning indicators show where next wave enemies will fall.
|
|
2. **Build & Adapt**:
|
|
- Draft new shapes (randomly offered).
|
|
- Place/Rotate units on persistent board.
|
|
- **Trigger Synergies**: Adjacency bonuses light up (Visual Feedback).
|
|
3. **Resolution**:
|
|
- Enemies fall/attack.
|
|
- Towers fire.
|
|
- **Player repositions shapes in real-time** to dodge incoming fire.
|
|
- **Player can active a the main tower skill**
|
|
4. **Outcome**:
|
|
- **Defense Breached**: Lose Health (Punishment).
|
|
- **Defense Holds**: Gain Gold/XP.
|
|
5. **Evolution**: Buy upgrades or Mutate blocks (Synergy scaling). Threats
|
|
escalate automatically.
|
|
6. **Repeat** until Death or Victory.
|
|
|
|
## Progression & Motivation
|
|
|
|
### Encounter Goals
|
|
- Encounters consist of a **variable number of waves** (RNG-driven difficulty/length)
|
|
- Some encounters feature **mini-bosses** mid-run
|
|
- The **final encounter of a scenario** is a **boss fight**
|
|
|
|
### Player Motivation Arc
|
|
- **Moment-to-Moment**: Hit synergies, exploit combinations, survive threats ("feeling clever")
|
|
- **Single Run**: Build scaling through gold; adapt to random shapes; defeat
|
|
mini-bosses and scenario bosses
|
|
- **Long-Term (Meta)**: Unlock new block types and permanent perks across runs;
|
|
expand synergy possibilities; enable new strategies in future runs
|
|
|
|
### Permanent Progression
|
|
- **Unlockable Blocks**: New tetromino types unlock over time, creating fresh
|
|
synergy combinations
|
|
- **Unlockable Perks**: Passive bonuses that persist across runs, increasing
|
|
player power and enabling riskier strategies
|
|
- Progression feeds back into motivation: "What can I break with this new block?"
|
|
|
|
## Core Mechanics
|
|
|
|
- **Tetromino Placement & Rotation**: Spatial puzzle element; player chooses
|
|
positioning and orientation on grid
|
|
- **Adjacency Synergies**: Shapes trigger bonuses when placed next to
|
|
complementary pieces; core depth driver
|
|
- **Persistent Board State**: Board carries between waves; placement decisions
|
|
compound and escalate over time
|
|
- **Shape Drafting (Random)**: Player selects from randomly offered tetrominos
|
|
or mutations; forces adaptive strategy
|
|
- **Real-Time Repositioning**: During enemy attack, player moves shapes to dodge
|
|
and optimize defense in slow motion
|
|
- **Encounter Market**: Shapes or Upgrades purchased with gold; modify base
|
|
stats and effects;
|
|
- **Resource Economy**: Gold collection from successful waves → purchases upgrades/mutations;
|
|
paces progression
|
|
- **Automatic Wave Escalation**: Threats increase autonomously each wave;
|
|
creates growing pressure
|
|
- **Enemy Telegraph**: Visible threat indicators before waves;
|
|
enables defensive planning
|
|
- **Mini-Bosses & Bosses**: Special encounters with unique attacks that twist
|
|
standard wave mechanics
|
|
- **Perk System**: Permanent unlocks that affect all game state (damage, costs,
|
|
synergy bonuses, etc.); unlock through meta-progression
