Cool game. I wish you included in the description that it's a jam game, because the concept is very interesting and fun, but the execution is rushed (no surprise given it's a jam game) and not really challenging. You can just spam bombs and solve everything, but thinking makes it fun.
It's confusing that unlike in Minesweeper, mines can exist on squares with a number on them. This makes the mechanics of the game much harder to understand at first. It's also a little unclear that you have to blow up the mines by placing bombs adjacent to it, it's not intuitive. At first, I thought I had to place the mines according to the numbers, since they are both explosives.
It's also strange how some aspects of the game are turn based and controlled by you, while others (bombs) go on in real time. I don't mind it, but again it's something people might have trouble understanding straight out the door.
Again, it's a nice idea, and I enjoy the way it makes me think. This mix of mechanics could definitely go places.
