Great gameplay, atmosphere and visuals. It took a while for me to understand the game (in fact, I only really got it after watching the gameplay showcase in your YouTube channel, awesome resource!). I think the game could benefit from a more in-depth tutorial. I understand the discovery / exploration aspect is a design choice and I appreciate it, but I can definitely see people giving up before realizing what the game is about (and missing out, as this is an awesome experience). Also, the font was a bit confusing to me, I thought the "8" was a "0" at first. Given how essential the coordinates are to the gameplay loop, I'd consider switching to something more readable. Awesome entry, congratulations!
