It's a great concept, but difficult to understand at first glance.  I just really want a way to exit or try again when I lose.  The music was great.

I love this game; it's simple, fun, and has much features. The sand falls by gravity in a way that was likely hard to do, and the music it's perfect with such a dynamic game.

Also, you can leave the map using grenades (and then you can't enter again, lmao)
