Great art, good story, and a very solid take on the mechanic flip! I really like how you ended the story with a cheeky jab at the character. I found myself enjoying the relationship between the characters a lot.
I may have found a bug, however. I missed the shot on the second try, and the game auto-rebooted right when the "raindrop" spawned, but after that, the raindrop didn't spawn and just soft-locked me in an empty land with no more bunnies. The same thing happened again in the 2nd try after I got past that section to the next gameplay and hit the R after the rain passed through the ground. It took me three times to eventually complete the game.
It was fun, but it can definitely be improved. Good job!
