What it does
2D Games is an agent skill from xenitV1/Antigravity-Workflows. 2D game development principles. Sprites, tilemaps, physics, camera.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Game development and Sprites and pixel art. The licence is MIT.
When your agent uses it
- Tasks that involve Game development
- Tasks that involve Sprites and pixel art
Example prompts
- “/2d-games”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit f0a1fa7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
2D Games loads about 547 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 196 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

2D Game Development
Principles for 2D game systems.
1. Sprite Systems
Sprite Organization
| Component | Purpose |
|---|---|
| Atlas | Combine textures, reduce draw calls |
| Animation | Frame sequences |
| Pivot | Rotation/scale origin |
| Layering | Z-order control |
Animation Principles
- Frame rate: 8-24 FPS typical
- Squash and stretch for impact
- Anticipation before action
- Follow-through after action
2. Tilemap Design
Tile Considerations
| Factor | Recommendation |
|---|---|
| Size | 16x16, 32x32, 64x64 |
| Auto-tiling | Use for terrain |
| Collision | Simplified shapes |
Layers
| Layer | Content |
|---|---|
| Background | Non-interactive scenery |
| Terrain | Walkable ground |
| Props | Interactive objects |
| Foreground | Parallax overlay |
3. 2D Physics
Collision Shapes
| Shape | Use Case |
|---|---|
| Box | Rectangular objects |
| Circle | Balls, rounded |
| Capsule | Characters |
| Polygon | Complex shapes |
Physics Considerations
- Pixel-perfect vs physics-based
- Fixed timestep for consistency
- Layers for filtering
4. Camera Systems
Camera Types
| Type | Use |
|---|---|
| Follow | Track player |
| Look-ahead | Anticipate movement |
| Multi-target | Two-player |
| Room-based | Metroidvania |
Screen Shake
- Short duration (50-200ms)
- Diminishing intensity
- Use sparingly
5. Genre Patterns
Platformer
- Coyote time (leniency after edge)
- Jump buffering
- Variable jump height
Top-down
- 8-directional or free movement
- Aim-based or auto-aim
- Consider rotation or not
6. Anti-Patterns
| ❌ Don't | ✅ Do |
|---|---|
| Separate textures | Use atlases |
| Complex collision shapes | Simplified collision |
| Jittery camera | Smooth following |
| Pixel-perfect on physics | Choose one approach |
Remember: 2D is about clarity. Every pixel should communicate.
