So I just played the demo and so far my opinion.
Your being dropped instantly in the game, you don't have any discription what the plant girl of choice does, would be a lot better if you can just left click the girl instead of the small green harvest because you won't rly use left click other then placing a girl.
As someone else mention the aim is kind of off doesn't exactly go to your pointer, a pause button or or something to allow reading what the plant girl does be nice. so far first 3 give resources where as the 50000 retaliates when hit.
so far it's maybe fun to try once but needs a lot of polishing before anyone should buy this game
