This is absolutely a minesweeper game, no question. but it's held back strongly by a lack of a proper interactive tutorial. if you had started with a single match 3 goal and only 3 mines total, for instance, we could have come to understand how it works intuitively. And the next step probably would be 6 mines match 4? And after that, maybe the first level you have currently.
I started to get the basic idea of what was going on after 5+ minutes of messing with it, but that's too much. I do hope you give it another try, I love the mashup of different genres here.
