Without weapons or resources, the only thing you've got to survive is a device that generates matter, but what if the sole usage of this device unleashes an unknown dark ancient power? Help this lost explorer to reach the way out of this powerful darkness in this abandoned citadel.

With this matter device as your only way to survive, deal with challenging puzzles and dangerous enemies, find hidden places to discover the dark story behind this doomed citadel or to discover hidden power-ups for the matter device.

Immersive pixel-art

Challenging levels

Being able to place your own platforms and walls is a big plus, and you will need id

Story in the visuals

Let the game tell you about what happened to this citadel and why everything is against you in this place

Hello! I liked your demo, it has good potential to be a great game though I would suggest a small tutorial to ease the player into the game and maybe a bit more diversity on the backgrounds. Aside from that you've made a good start and I wish you like in this and your future projects! I made a let's play of your game here-

Hi Miss Blue... Woww! I'm really glad you played my demo! Thank you for your time doing this video and your feedback, this means a lot for me, specially now. 

About the game, unfortunately you played a bit outdated version, the new one has gameplay fixes at the 2nd level and also that tutorial which I saw how much you needed in the video haha! I was laughing as crazy when you tried and failed so many times :D sorry for some stressful moments I saw that shouldn't have happened, definitely will fix those.

About the backgrounds, that's on my bucket list, after I finish all the game mechanics I have in mind, I will focus  on aesthetics (there  are actually some examples  about what I have in mind for aesthetics in the landing page)

Again, thank you for playing and hope you play it in the future with or without video ;)


You're more than welcome! I'm really glad you enjoyed it and could take something away from it (even when I was failing miserably ^-^') I'm glad you'll be working on the game more and I'll be sure to check in every so often to see your progress :D
