I really really like the aesthetic of the intro (esp. the music), it made me excited to play the game.
The shooting sound effect hurts my ears a bit (it is very high-pitched). It is also hard for me to tell when I need to break all the eggs vs. let them go. In a lot of stages, it seems I can just walk to the exit and ignore the eggs.
Swapping back and forth between the two objects is fun! Movement feels good.
I find it a bit hard to tell when I'm doing damage to the "boss" enemy, even with the sound effect.
I also tend to skip over tutorial stuff, so it took me a bit of time to figure out that I was swapping to the coin thing by hitting space. Maybe having more feedback when you swap between them in the same room would help.
