That was really fun, the level design is really good, especially liked the final two levels.
Loved the idea and mechanic of scaling up so huge.
the style is good and charming.
it was also funny sometimes, each level's goal is to just get a burger. And the end goal is to fight the sun. LOL
I did face some issues with physics of the game, bumping into the switches sometimes launched me really high, my suggestion is don't rely too much on the physics engine for everything and possibly make colliders for switches a trigger. Hope this is helpful :)
Overall, I really liked it. Good job!
