2/5. When I'm told "build the following 4 buildings immediately, in this order" and I lose if I deviate from that instruction, it takes the "strategy" out of the game. Also I have no idea what is going on.
Since I do not enjoy: memorizing which bugs are coming, and when; randomly losing flowers; and randomly hitting bugs, depending on how the flowers fly, I rate this "game" 1/5.
Much weaker modified version of Desktop Tower Defense. And for those who think this came before- please note that the game itself acknowledges that it is based on DTTD under "Help".
