Z2S: zombie survival strategy

I like the basics of the game, simple and focused. Advancement is brutally slow and repetative. not enough to keep me interested. Conceptually it was really good. Continued to play and finally on the i dont know how may games I was able to successfully survive and research/build lot of stuff. Then returned to the city to try defeat some of the more challenging buildings only to find the scaling had cracked up all buildings to impossible levels. Pointless. Needs some work.

Its fun, but the text is barely legible, and i can't figure out how to almost anything.
