Interesting take on the theme. But perhaps the tams could multiply after a while, with different types of tams have differing needs. For example, some may want certain types of toys to keep them entertained.
Amazing options menu. Most comprehensive I've seen in a game jam. This was really impressive, even if most people didn't seem to notice.
Some minor issues: scrolling the instructions also scrolled the game. Dragging the boxes with left click interferes with left clicking the buttons. Make mouse right click drag the box. A zoom option would really have helped out.
