I feel like this is one of those games I would fall in love with and play at least till the end... If it weren't for the fact that I had no idea what to do anything. I understood that part where I had to produce those "biostuff" generators, but how do I attack the city? It was just mostly guess-spamming the screen with different plants. I had a really hard time with the controls, I did not understand the cursor's position (it kept showing a little grey square underneath it all the time, sometimes showing through the buildings, sometimes not).
I didn't notice the city fighting back the plants if it's implemented. Overall, I love the idea but the game needs a bit more polish :)
