Chrono Robot

Play:

Full screen Touch: Not supported - a full source scan found no touch/pointer handlers anywhere in the gameplay code, only keyboard bindings · Keyboard: Arrow keys, WASD, or ZQSD to move and jump, Space to use the time machine

About:

A puzzle-platformer built for GameDev.js Jam 2023 (tied 7th, Open Source category), in explicit homage to the Flash classic Chronotron. Movement is arrows/WASD/ZQSD, Space activates the time machine, confirmed genuinely functional: a real held key press moved the robot across a level, and a real held jump key produced a genuine mid-air jump landing on a raised platform. Correctly shipped desktop-only, since the entire gameplay source only binds keyboard events, with no touch or pointer handling found anywhere.

Credits:

Made by A time-travel puzzle-platformer, homage to Chronotron, 2023. Published here with credit to its author, who stated no licence for it. Source code.

Phone check: 2026-09-08: confirmed the in-level instructions (arrows/WASD/ZQSD to move, Space for the time machine) match the actual keyboard.js source exactly, with a full source scan finding no touch/pointer handlers anywhere. Played on desktop: a real held D-key press moved the robot right, and a real held jump key produced a genuine mid-air jump landing on a raised platform. No LICENSE file exists in the source repo (submitted to the jam's Open Source category with all code visible, but no explicit license grant), so shipped with licenseUnknown. No third-party analytics found; one optional Web3 leaderboard link only opens on explicit user click, never automatically.

No licence stated. A time-travel puzzle-platformer, homage to Chronotron published this game without saying how it may be reused, so it is hosted here on the strength of credit alone: their name, a link to their own release, and nothing altered but what it took to run. If you are the author and would rather it were not here, get in touch and it comes down the same day.
