it is a "game about digging a hole " simulator, but it has some problems
it is really easy to get stuck in the terrain, with the only way to get free to dig your way out, which on low battery is a death sentence.
and if you do manage to dig straight down, then the game is over in like 10 minutes.
it needs some teraain optimization to not get you stuck, some mopre dept and story telling and it is good.
but right now, it is ok
