I'm entertained by this. The presentation adds tension, and the first person perspective really shakes up my intuitive grasp of the space. But as someone who has spent entirely too many hours in minesweeper, I do have a couple nitpicks.
1) When you unmask a 0 dancer, it looks like the game is supposed to automatically unmask every dancer adjacent to them, which is well and good. But it misses (fails to unmask) the diagonally-adjacent dancers, which should presumably also be unmasked.
2) When you place the final rose on the final vampire, the game ends immediately, even if there are dancers left you haven't unmasked. This is the opposite of the classic victory condition, where marking the mines isn't actually the goal, but rather uncovering every non-mine square. By ending the game in victory when every vampire is marked, you allow the player to brute force a solution. Of course, this can be an advantage, in that it allows players to solve the common "last 50/50" type situations where there's only one vampire left but no way to know which of two dancers it is. But it still has the potential to degenerate into players just brute forcing rose locations once they get close to the end.
If it matters, I was playing the windows version.
