Fast Prototyping
Ship micro-levels in minutes with modular rulesheets and hot-reload telemetry. Iteration loops built for observation and delight.
- • Visual scripting grid
- • Deterministic runtime for predictable tests
- • Lightweight telemetry & share links
Play Modes & Economy
Daily arcade runs, co-op puzzles, ranked ladders, and optional community curation tokens create layered incentives.
Gallery — live prototypes
Snapshots of recent jams, player runs, and modular levels. Tap into each build, fork it, or queue it for study squads.
Featured Jam
Community jam with weekly themes and curated rule-sets. Winners become templates for teachable mechanics.
Mod Shop
Fork public levels, tweak parameters, and share diffs. Every mod is its own playable artifact.
How it works
Seed · Iterate · Observe
Create a seed level, invite a small test cohort, push a tweak, and watch tactics emerge. Short loops prioritize learning.
Tools & Runtime
A compact deterministic engine, scriptable rulesheets, and telemetry streams that respect privacy by default.
Voices from the lab
“ArcShift turned a sandbox idea into a weekly habit. Our team ships prototypes with meaningful player data in single afternoons.”
— Mira K., designer
“Players discover emergent rules that surprise us. That kind of discovery fuels better designs and better systems.” — Omar T., researcher
