Awesome game graphics! Felt really juicy! I think you definitely were onto something with the minesweeper concept and might have missed the opportunity to add a really cool twist on the game like uncovering artifacts while dodging the traps or even just multilayering minesweeper games to show you progressing down the cave and make it a high score chasing game, but a cool game nonetheless!
Just a few technical things too: many times I end up clicking once and getting one block revealed or end up clicking a bomb first try and every 2-3 runs I'm left with a handful of situations where I'm forced into a 50/50 (a really common one is two blocks covered surrounded by "one" tiles forcing me to guess which is which)
Just a few things I thought I'd bring to your attention (if it wasn't already found hahahaha) All in all amazing job!
