Thanks for the comment! We loved, that you spent a good time with our game.
If you play a little longer, you may find how the rabbits get sick and sneeze on each other. And even further we have implemented the RABIES mechanic. You can try further levels with it too :) just use skip button for it (it placed on right side of level start button). Level 6 for example have this mechanics) Give it a try for more fun :D
