Michiru's hat is hungry! It will eat Deer or Snowmen. 

Play as Iori and build snowmen to feed the Hat until it is full to avoid becoming a meal yourself.

Move with WASD or arrow keys, and pick up and drop Snowballs and Carrots with  Space.

Simply walk into snowballs to roll them into bigger snowballs. Pick up and drop a snowball near another snowball to stack them. Drop a Carrot near Michiru to make it magical.

Stacking three snowballs and attaching a magic carrot brings the snowman to life and draws the Hat to eat it instead of you. Feed the Hat until the hunger bar is full to win.

(Picking up and combining things might not work properly if there are multiple objects close to eachother. Moving away, and moving close again, can solve the issue)
