# Tiny Crate > A free browser puzzle platformer about one very small crate. Carry it, throw it, toss it, push > it and stack it to reach the lift in 36 handcrafted rooms across five worlds. Every room hides a > note. There is no AI lane, no sign-in, no API and nothing metered: the page is free to everyone > and runs entirely in the browser. ## What it does - 36 rooms in five worlds (Workshop Floor, Boiler Room, Cold Storage, Loading Dock, The Attic), each one a single screen or a short scrolling room, unlocked in order. - Mechanics: carry / throw / toss / drop / push crates; coloured switches that hold blocks solid and pop crates from hatches; spikes that hurt the player but not crates; one-way ledges; gates that seal into wall after something passes; bounce pads that launch anything (thrown crates keep their speed); one-tile crawlspaces that knock a carried crate off; hidden areas drawn as wall. - Every room ships a built-in solution replay (press H) produced by a search over the game's own physics, so every room is provably solvable. Par times derive from those solutions. - Ghost races: your best run in each room replays as a translucent ghost. - A room editor: paint tiles, test-play, run the solver ("Check solvable"), save drafts in the browser, and share a room as a link (the whole room is encoded in the URL fragment). - Remappable keyboard controls, gamepad support, touch controls, adjustable sound and music, reduced-motion and screen-shake options, save export/import. ## How to use it Open https://tiny-crate.skillsafe.ai/ and press Play. Arrow keys or A/D run, Space jumps (hold for height), E picks up a crate; E while running throws it, Up + E tosses it straight up, Down + E drops it. R resets the room, Esc pauses, H shows the solution. Add `#room=2-3` to the URL to jump to an unlocked room; `#e=...` links open shared rooms. ## Sources and attribution A browser-native reimagining of "Tiny Crate", the crate-chucking puzzle platformer by HarmonyHoney (https://github.com/HarmonyHoney/tiny_crate), released under the Unlicense.
