Desktop Dungeons isn't this game at all. While a similar style of resource management, and a great game in it's own right, it's lacking the "minesweeper-y" exploration tactics.

It's pretty similar:

- a grid of hidden tiles containing monsters

- that you fight by clicking on

- where you balance exploration and combat

- using your HP and level-ups as resources

I'd say this game was directly inspired by Desktop Dungeons (which isn't a bad thing!)

I’d say DemonCrawl is a more likely inspiration since it is also a minesweeper variant.
