I loved the idea of a minesweeper-esque puzzle game, nice work! Using the Geiger counter as a sort of metal detector was a unique concept, and while it could've been explained better in game - I spent my first two rounds randomly digging around and finding nothing - it was still a fun mechanic. Some variety would've been nice in the game too, like powerups you could dig up, or some obstacles, which would've helped make it feel a bit more engaging. The artwork was really nice, especially in the menu, and the sound design helped make the game feel more hopeless, which was an interesting aesthetic to go with - in a good way! Overall, it was a pretty fun puzzle game, with a lot of potential ways to take it in, so good work on it! 

The idea it's very interesting, i like the use of the Geiger and the sound, simple yet interesting game!
