Glad you find the game fun!
The original idea was to limit the movement by cells as if this game is to be played on a phone. Players will be swiping left, right, up, or down to control the slime. With each swipe the slime move by one cell. But later in development I just do not have the time to make it work as intended. So I just stripped the idea of moving by cells but still limited the number of input a player can give. :D
