8biter Game Jam #1
“Challenge yourself to build the most compact complete game ever — make every byte count!”
8biter Game Jam is a recurring jam celebrating a forgotten mastery of game development:
Fitting the most creativity, gameplay, and personality into the smallest possible space.
Inspired by the 8-bit era—where developers worked with tiny memory budgets and limited hardware—this jam challenges modern devs to rediscover that discipline and turn constraints into strengths.
This is not about nostalgia alone. It’s about craft.

“Whether you’re an indie newcomer or hardcore jam vet, 8biter brings out your tightest design skills. Compete to build elegant games that defy file size expectations!”
THE PHILOSOPHY
Early game developers didn’t have:
- Gigabytes of storage
- Massive engines
- Unlimited memory
They had:
- Clever tricks
- Smart reuse
- Tight design
- And serious technical skill
8biter Game Jam exists to celebrate that mindset and challenge developers to push themselves creatively by doing more with less.
THEME
To be announced when game jam starts.
Interpret the theme literally or creatively, but it must be clearly and meaningfully present in your game.
CONTROLS (REQUIRED CONSTRAINT)
To honor classic 8-bit hardware limitations, all games must be fully playable using only the following controls on controller or keyboard:
- D-Pad / (Up, Down, Left, Right) / (W,S,A,D)
- A Button / (Z) / (Space)
- B Button / (X) / (M)
- Select / (Shift)
- Start / (Enter)
Control Rules
- No additional buttons or inputs may be required
- Keyboard, controller, or touch inputs are allowed as long as they map cleanly to the controls above
- All core gameplay must be achievable using this control set
This constraint is intentional and should influence:
- Game mechanics
- UI design
- Menus and interactions
GAME REQUIREMENTS (ALL REQUIRED)
Your game must include:
- One complete level
- At least two enemy types or puzzles
- At least one collectible or upgrade
- One final boss encounter
- A clear ending or win condition
This is a complete game challenge, not a tech demo.
SUBMISSION REQUIREMENTS
To keep the competition fair across engines and languages, two builds are required.
1: Browser Build (Required)
- Must be playable directly in the browser on itch.io
- Must contain the entire game
- No downloads required to play
2: Windows PC or MAC OS Build (Required)
- Must be playable on Windows or Mac
- Must contain the same content and features as the browser build
- No demos, stubs, or reduced versions
❗ Both builds must be functionally equivalent.
FILE SIZE CALCULATION
Your Total File Size is calculated as:
Total Size = Browser ZIP size + Windows ZIP size
- ZIP compression is allowed and encouraged
- Only the uploaded ZIP sizes are counted
- Unzipped size does not matter
JUDGING (STANDARD GAME JAM CRITERIA)
Games will be judged using common, familiar jam categories.
Each category is rated 1–10.
Gameplay / Fun
- Is the game enjoyable to play?
- Do the mechanics feel good?
- Is the challenge fair and engaging?
Visual Readability
- Is the game visually clear?
- Are enemies, hazards, and UI easy to understand?
- Is the visual style consistent?
Audio
- Do sound effects and/or music enhance gameplay?
- Is audio feedback clear and appropriate?
Theme Use
- How well is the Dracula theme integrated?
- Does the theme influence gameplay, not just visuals?
- Does the theme feel intentional and meaningful?
Controller Use
- Does the game make effective use of the limited control set?
- Are controls intuitive, responsive, and well-mapped?
- Does the control scheme feel intentional, not restrictive or awkward?
Base Score = Gameplay + Visual Readability + Audio + Theme Use + Controller Use
FILE SIZE MULTIPLIER
Where efficiency is rewarded
After judging, each game’s Base Score is multiplied by a size-based modifier.
Smaller games receive a larger bonus. Larger games receive little or no size bonus.
Size Multiplier Table (Total ZIP Size)
≤ 50 KB × 2.00
≤ 100 KB × 1.80
≤ 500 KB × 1.65
≤ 1 MB × 1.50
≤ 5 MB × 1.35
≤ 20 MB × 1.20
≤ 50 MB × 1.10
≤ 200 MB × 1.05
≤500MB × 1.00
Final Score = Base Score × Size Multiplier
Fun and creativity come first. Efficiency separates great entries from good ones.
ALLOWED TOOLS & ENGINES
- Any engine or programming language is allowed
- JavaScript, C/C++, Godot, Unity, Phaser, Pico-8, custom engines — all welcome
- Optimization, procedural techniques, and clever reuse are encouraged
There are no engine bans, only tradeoffs.
DISALLOWED PRACTICES
- Reduced or placeholder builds for one platform
- Games that do not fully run in the browser
- Missing required gameplay elements
- Misleading ZIP uploads
BONUS AWARDS (JUST FOR FUN)
These do not affect final rankings:
- Smallest Complete Game
- Best Fun-Per-Kilobyte
- Best Use of Dracula Theme
- Best Audio
ABOUT THE 8BITER GAME JAM SERIES
8biter Game Jam is built around one core idea:
Limitations create better developers.
Each jam explores a new constraint inspired by classic hardware:
- File size
- Visual limits
- Control schemes
- Genre restrictions
All focused on rediscovering the lost art of efficient game design.
READY TO PROVE YOUR SKILL?
Strip it down. Optimize everything. Make every byte count.

FAQ
What engines or tools are allowed?
Any engine or programming language is allowed. JavaScript, C/C++, Godot, Unity, Phaser, Pico-8, and custom engines are all welcome. There are no engine bans — only size tradeoffs.
Can teams enter?
Yes. Solo developers and teams are both allowed. There are no team size limits.
How long is the jam?
The jam runs for [9 days]. The exact start and end times are listed at the top of the jam page.
Do assets have to be original?
No. You may use pre-made or previously created assets, as long as you have the rights to use them and they fit the jam rules. Proper credit is encouraged.
Does the game have to be playable in the browser?
Yes. A browser-playable build is required for judging. A desktop build is also required for file-size comparison.
Can I use keyboard, controller, or touch input?
Yes. Any input method is allowed as long as it maps cleanly to the required controls: D-Pad, A, B, Select, Start.
How is file size measured?
File size is calculated by adding the Browser ZIP size and the Desktop ZIP size together. Only the uploaded ZIP sizes are counted.
What happens if my game exceeds the size limits?
There is no hard size limit. Larger games simply receive a smaller size multiplier.
Can I update my submission after the deadline?
Try to submit your best final version before the deadline.
