During this Jam participants build small games on RIVES (RISC-V Verifiable Entertainment System), a fantasy console that can run small games written in any language that compiles to RISC-V. RIVES can natively verify and store submitted gameplay files as rewatchable tapes and add players to leaderboards. RIVES lets you create cartridges, and compete for the top spot on custom leaderboards.
