This game had a very unique mechanic somewhat reminiscent of many game's fishing minigames, and in this game that meant hovering over a smiley face to cum when the cum bar reached the top. Uniquely, though, there was a new mechanic where rapidly shaking the mouse caused the cum volume to increase so long as the smiley face was at hovered over at the very end. While this didn't change the game to be the most fun I have ever had, it certainly made gameplay a bit less mundane.
