I really liked the idea here! This was a fun almost minesweeper-like game that I could see polished and sinking a few hours into. It was pretty cozy until I started drilling further and couldn't make it back to the surface in time. I got greedy! My biggest complaint here would be the dialogue implementation. The interact button should display the final text faster and not skip completely. I also didn't like the text going behind the player, making it hard to read. In the end, got a black screen after losing my drill and then trying to enter it again. My guess is you moved the drill off-screen and the camera jumps to it when you try to re-enter. Great entry overall!
