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.
- 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!)
