Hey,
Great game and i love the improvements...
The rabbits quest make me think to an other wich could be fun too...
We al know that rabbits are really fast, but rabbits are also well known for an other.... ability
So you could make a race against time in which you have to reach lvl XXX (100; 150; 200) with 1 rabbit in the column, then after some time, like 12h, reproduction miracle, they are 3 rabbits (1st and 2nd column) after 24h, 6 rabbits (1st, 2nd and 3rd column) and after 36 or 48h : Game over...
It's just an idea that i found fun, i hope you find that fun too :)
Sorry if my english is not perfect, it's not my mother tongue :D
Thanks for the feedback. =)
