Interesting take on the theme and very fine grade art! Had not chance miss the game with such a name. Being a geographers myself, thanks you for warming my heart, I always thought geographers and cartographer specifically are underrepresented in video games:)
As for the feedback:
- A simple crouch animation, even just pose for the character when he is behind the stone would make the game feel better.
- Some simple short SFX when the monster detects you would also help to perceive the game and dive deeper into the experience.
