A prototype speed precision platformer made initially for GameDev.tv Game Jam 2026.

Jump across dangerous platforms, overcome mechanical obstacles, and uncover the connection between each mysterious level.

Inspired by retro arcade classics, this fast-paced pixel adventure combines precision platforming and old-school challenge.

Current playable web version: 0.0.0.3

Work in progress prototype:

  • Limited amount of levels
  • Some other stuff might be broken or missing


Credits:

  • Pixel Platformer Sprite Sheet and Pixel Platformer Industrial Expansion Sprite Sheet by KenneyNL, modified by Nox.
  • Sound Effects from Pixabay and Uppbeat.
  • Music by Fesliyan Studios.


To-do:

  • Score system
  • Upgrade modules



Latest Patch Notes:

  • 0.0.0.3
    • New Features
      • Added jump sprite animation
      • Added a new sprite color animation to indicate battery level. Part of the WiP to remove intrusive UI elements.

      • Added coyote time. Now jumps should be a little more forgiving. Still looking to balance it.

    • Bug Fixes
      • Fixed a bug that would cause the level to restart after starting the exit sequence when the door was interacted with once the 'emergency battery' mode had been activated on Robo.
    • Bugs
      • There seem to be some platform variations that have issues with collisions. Looking into it.

I love the art — probably because I’m a big fan of pixel art ❤️. It’s understandable that some features are still missing, but I’m not sure if the jumping and losing time is a feature or a bug 😄. Honestly, even if it was a bug, I’d keep it as a feature haha. Also, the music when transitioning to another room really reminded me of old SNES games like Tiny Toons. Nice work!

I really like the artwork. It's fun to jump around!
