Most of the mechanics in the game serve no purpose. Many tasks complete themselves after a time limit. There are also some arbitrary power ups that have too many negative effects and, after a very early stage in the game, it becomes impossible to obtain more. The game is far too repetitive for the massive length that it spans(after several hours I was only 2% done). The least sensical part of the game is the point system. You earn points based on how quickly you finish tasks for each new isotope, but for the last portion, it is nearly impossible to earn any points at all. However, the game has no way of giving the points any value besides the handful of useless upgrades. In summation, the game's unchallenging interface, the endless(and endlessly long) gameplay, and the pointless points, the game suffers from a lack of any reason to play the game.
