I really enjoyed this! The controls weren't immediately obvious, I thought the rabbit was jumping automatically at first, but when I figured it out, it was very cool.
I also really appreciate how you found a way to develop the mechanic within such a short time with the carrot switch, a sick idea that could been developed further.
My main problem with the game would be the level exit, it takes too long and it doesn't really have a purpose; even if you fail because you were only half way up the elevator when the level ended, the win screen will override the lose screen and you can leave once the bunny hits the top of the elevator.
Overall this is a creative game with solid progression, making it over 6-8 hours is wild. Great job!
