You can lap the time with your friends and see how fast you click.You can squash them fully with your plants, if you finished them you lose.there's only 1 level in the game. You can even move your plant and click to clone, have fun squashing slimes !!! Sorry that I forgot to put the top row with plants...
drag the plants with your mouse click to clone you can move the slime anyway you want beware, slime can eat your clones so,beware if you filled the whole moat with all type of plants, you win.
