48-Hour Game Jam Quick Recipe

How to pair these tools for maximum velocity without getting bogged down:

Step 1: Visuals

Kenney + Poly.pizza

Grab CC0 modular 2D or 3D packs. Don't make custom art until gameplay is fun.

Step 2: Level Design

Sprite Fusion

Assemble tilemaps directly in the browser and export directly to your engine JSON or PNG.

Step 3: UI & HUD

Game UI Database

Inspect HUD layouts of proven games to avoid messy, unreadable interface hierarchy.

Step 4: Audio

jsfxr + BeepBox

Synthesize 8-bit sound effects in seconds and compose catchy loopable chiptune tracks.
