  • Added ability to change window size (F1).
  • Added more color palettes in case you'd like something other than the original green (F2).
  • Added ability to mute audio (M).
  • Replaced "Jump+" upgrade (which wasn't even accessible due to glitch).
  • Minor adjusts to world design.
  • Major adjustments to HUD displays.
  • Remaining To-do list:
    • replace/fix sound engine
    • add more music, update sound effects
    • complete intro
    • fix "dasher" enemy glitch
    • some world decoration and finalize tile set
    • any new bugs found in this release!

Unknown Planet is a Metroid-vania, jumping platformer. You don't shot anything. The world is designed to kill you, so expect a high death curve. Unknown Planet was originally created in 8 days for GBJAM 5.

A great big thank you to Mark Sparling for the amazing soundtrack (check him out: https://soundcloud.com/marksparling).

This game is amazing, frustrating at times I have to admit, but still amazing! The design is pretty and simple, sadly I don't keep the music on because I die too often but it's really nice. And I LOVE all the color palettes

Update: just finished the game, I still love it

Cool game, I played it to 94% completion this morning.
So let's get in again and find the remaining stuff...


Nothing saved at all?
No save feature anywhere?

Well then, fuck it! >:-(

I'm impressed by the 94%. It's the highest (reported) percentage so far. I know it doesn't bring back your previous progress, but I am working on a save/continue feature in my post jam version. Along with audio fixes, a map, better progress tracking, intro exposition, in-game instructions and a few tweaks to the handling/physics. I've been busier with work/life than usual so it isn't progressing as fast as I'd like. I'm hoping to have an update here soon.

Some sort of map would be nice :-)

If there wasn't one before there is now.

I have no words for how much I loved this! It reminds me a lot of Super Mario.
