Jam Guidelines

• Optional themes to use for inspiration: Gifts, Cycle, Journey
• We'll have a week of community evaluation on itch.io after the jam closes, with criteria: fun, unique, polished, graphics, sound, & controls.
• No NSFW nor discriminatory content (see Contributor Covenant 2.1 for what that means)
• The jam is a week and more to accommodate different schedules. Don't feel like you need to spend all your time on it during the week. Do what works for you!
• You don't have to share your source code, but it's encouraged!
• If you've already started something for WASM-4, feel free to finish and submit it.
• If you've already submitted a WASM-4 game elsewhere, start something new. (But feel free to reuse some code or assets.)
• We'll announce one or more optional prompt themes when the jam starts for those who want some inspiration to get started.
• No prizes, but highlight games will be featured in a video on the Context Free channel on YouTube.

Have fun, and make awesome small things!
