Junk Jack Development Roadmap

Hello everyone, we’re making good progress on Junk Jack for desktop platforms, so we thought to share a roadmap to with you!

Starting from this roadmap, our primary task is to have the plethora of current features of Junk Jack X correctly ported and adapted for desktop platforms. So basically our schedule is the following:

  • finish porting the current product to let it run on desktop platforms
  • early-release the game
  • follow the feedback and what the users want most
  • integrate large changes in the game to make full advantage of the increased characteristics of desktop platforms (screen size, cpu/gpu power, flexible controls) over the time

The interesting part will come after our initial release, when we’ll be able to raise the bar and add many interesting features that have been in our construction yard for so much time, especially if we’ll be able to establish a good user base that can provide useful feedback to us!

As people that played our games on iOS already know, we’re quite dedicated to this game and we’ve been able to add so many features over the years on the mobile counterpart that we’re really excited to be able to enforce the same dedication for the desktop version of the game!

Hi guys and gals! It’s time for a little update, we’re really busy working on the game engine, constantly adding content and features to enhance the gameplay experience!

Currently we’ve been able to launch the game on Windows and OS X operating systems but much work is still to be done! 

Today we present you the Junk Jack star map! 

You start the adventure in Terra, then, by finding and assembling portal pieces, you will be able to explore new worlds as shown in the map.

Each planet is carefully hand crafted and unique in its own way, with different themes, monsters, equip pieces, blocks, and much more stuff. 

More details about the planets and its contents are coming soon, so stay tuned!
