This game reminds me a bit of Old Jim's Convenience store from IFComp 2019. Both feature an old, abandoned structure underneath which is a large mining area.
This game is the author's first game, and the lack of beta testing shows. The interesting layout and rooms are negatively impacted by under-cluing and by exits which stop working once you use them and runtime errors.
My 5-point scale:
-Polish: This game is not polished.
+Descriptiveness: It is relatively descriptive
-Interactivity: Bugs cause quite a few problems
+Emotional impact: I found parts of it quite fun (like the result of using dynamite)
-Would I play again?
