I like the idea of a clicker game but my main problem with this is that there's a lot of clicking ... and no game. One of the key characteristics of clickers is getting a reward for work done, which can be accelerated by smart decisions by the player.
Perhaps it might have been better to theme the emoji/emotion with the mechanic, for example clicking a drug might produce a rush of happiness but have long-term negative consequences.
Overall an interesting idea but needed a bit more development.
