Thank you for giving our game a play!!
The original idea was to be made as a 2D pixel/ASCII platformer (for Unity, or Godot), that's our favorite medium personally. We developed a lot of map ideas and assets, but realized after a few weeks that, with the scope we wanted to capture in a demo, we would be biting off more than we can successfully chew before the deadline.
But we really wanted to hone in on the atmosphere and build the story behind our game, and then build more interactive mechanics that make players feel more immersed in this world. Puzzle elements are the next development step for sure, every dark narrative twist should feel like it's something the player was clever enough to get to the bottom of. Making this prototype system really helped us as the creators understand how this vision looks in its most basic form.
