A little bit disappointed - When you get to around 30k likes, it suddenly changes to NEGATIVE 30k likes, and you have to get another 30k+ before you're back at zero and can start giving carrots again. I did it twice in a row just to make sure it wasn't a random fluke.
That said, the fact that I got to 30k (which switched to -30) then to 0, then back to 30k, (which then switched to -30k for the second time, at which point I called it quits) tells you that I was having a good time. Cute bunnies, relaxing game. The only improvements to be made are fixing the likes-turn-negative bug, and maybe including a "high score" record so you have an incentive to play again and beat your personal best.
But if you're just looking for a few minutes of bunny cuteness, try this out and have a calming time :)
