Very creative and certainly fun to play. Though somewhat fitting chain reaction, it is hard to see it. I would personally suggest adding abilities such as skipping a tile, and additional hazards like a dragoon falling onto the board the longer you survive. Really make it chaotic to get that chain reaction theming. Right now the only thing to end it is the timer, as the game itself is easy to survive. It is certainly a very solid game. I am hoping you refine this into something more after the jam! Has a lot of potential!
