Really cool game! The idea and presentation are solid, and the theme is very well represented here, great job. This should have a lot more ratings!
The map is very large, which helps giving a sense of desolation and dread. I did run out of energy every time though, feels like the limit is a tad low. Either that or making loops is harder than it looks. I also ran into a bug once where it tried to place a tile on top of the last placed tile, and it wouldn't let me place any tiles after that,
