I'd had my eyes on this little game for a while, which seemed like a cousin to the very attractive family of underground and mysterious space exploration games (I'm thinking of Grant Howitt's The Rules of the Deep but also the sublime Veins in the Dark of course), with, indeed, a small system to generate infinite and dark spaces.
This is a game that's all about sketches, but with a system of rules that supports this atmosphere of survival / anxiety: adapted inventory rules, a logic of memories serving as health points, a very nice bestiary...
It makes me want to go underground once again, and that's not just a question of high temperatures.
