Anyway, Who's my favourite bunny? Well, for me, it's Mochi (flower level at cherry and very cherry), follow closely by Hoplynn (flower level at cherry).
Nice, this is a very good game. Simple yet fun.
Tips: For those of you who find the game hard, try to corner the border bit by bit. This method should be a little easy to win.
