Nice art style and poster; I'm sure that's bringing in the wealth of players!
The game itself is a nice little idea and could definitely find a nice home on mobile, or the like, in its current format.
The choice of voices sound effects is also quite cute; but adding a little more variation or pitch shifting to them would help them not feel repetitive after a couple of levels :)
I felt there could be a little more to the death animation to really sell the death, instead of instantly starting the level over. And I'd also tweak the music a little to ensure the loop is satisfyingly invisible, as it's currently a bit of a stark repeat.
Other than that, cute game and good execution!
