To The Core is a (relatively) short incremental game. Some said that this game has zero replayability, but I beg to differ, for I have completed the game almost a dozen times by now. I find this game to be a good method to release stress when things aren't going well in life, like whenever you wish you had the button to destroy the planet or something. Just pure happiness seeing the number goes up for a few hours.
Beware though... the game is kinda unstable, buggy and laggy.
