9	### Sprite Organization
10
11	\| Component \| Purpose \|
12	\|-----------\|---------\|
13	\| Atlas \| Combine textures, reduce draw calls \|
14	\| Animation \| Frame sequences \|
15	\| Pivot \| Rotation/scale origin \|
16	\| Layering \| Z-order control \|
17
18	### Animation Principles
19
20	- Frame rate: 8-24 FPS typical
21	- Squash and stretch for impact
22	- Anticipation before action
23	- Follow-through after action

27	## 2. Tilemap Design
28
29	### Tile Considerations
30
31	\| Factor \| Recommendation \|
32	\|--------\|----------------\|
33	\| Size \| 16x16, 32x32, 64x64 \|
34	\| Auto-tiling \| Use for terrain \|
35	\| Collision \| Simplified shapes \|
36
37	### Layers
38
39	\| Layer \| Content \|
40	\|-------\|---------\|
41	\| Background \| Non-interactive scenery \|
42	\| Terrain \| Walkable ground \|
43	\| Props \| Interactive objects \|
44	\| Foreground \| Parallax overlay \|

48	## 3. 2D Physics
49
50	### Collision Shapes
51
52	\| Shape \| Use Case \|
53	\|-------\|----------\|
54	\| Box \| Rectangular objects \|
55	\| Circle \| Balls, rounded \|
56	\| Capsule \| Characters \|
57	\| Polygon \| Complex shapes \|
58
59	### Physics Considerations
60
61	- Pixel-perfect vs physics-based
62	- Fixed timestep for consistency
63	- Layers for filtering
64
65	---
66
67	## 4. Camera Systems
68
69	### Camera Types
70
71	\| Type \| Use \|
72	\|------\|-----\|
73	\| Follow \| Track player \|
74	\| Look-ahead \| Anticipate movement \|
75	\| Multi-target \| Two-player \|
76	\| Room-based \| Metroidvania \|
77
78	### Screen Shake
79
80	- Short duration (50-200ms)
81	- Diminishing intensity
82	- Use sparingly
83
84	---
85
86	## 5. Genre Patterns
87
88	### Platformer
89
90	- Coyote time (leniency after edge)
91	- Jump buffering
92	- Variable jump height
93
94	### Top-down
95
96	- 8-directional or free movement
97	- Aim-based or auto-aim
98	- Consider rotation or not
99
100	---
101
102	## 6. Anti-Patterns
103
104	\| ❌ Don't \| ✅ Do \|
105	\|----------\|-------\|
106	\| Separate textures \| Use atlases \|
107	\| Complex collision shapes \| Simplified collision \|
108	\| Jittery camera \| Smooth following \|
109	\| Pixel-perfect on physics \| Choose one approach \|
110
111	---
112
113	> Remember: 2D is about clarity. Every pixel should communicate.
