This is intended. The bunnies want to get to the carrot and then to the register in the end. are you sure that carrot crate isn’t blocking their path?
oooh got it! by the phrasing in the game page, it sounded like only bunnies would block each other, thanks for taking the time to explain, it's so addictive! i'm in level 9 already and came back to reply because i'm stuck only :P
Awesome, glad to hear you liked it!
