I love the pixel art! A very simple yet fun idea. Its great how you incorporated the classic movie disguise with two kids trying to get the food.
I only noticed 2 things, on the second level it was really hard for me to get the hat as Timmy wouldn't line up in position to grab it. And I also got stuck on a plant. I believe perhaps friction of some sort can help the player slide off of the plant so that way it prevents them from getting glitched. Overall, I think its great!
Definitely hoping to see more in the future :)
