So, let's start:
- Unskippable intro - WHY WOULD YOU DO THAT? >:
- I won't comment on language, as most likely I'm also making lots of mistakes.
- Whether you win or lose seems to heavily depend on how many cities you get when level is created.
- Graphics looks nice, but cities don't really match style of other tiles.
That's about it. Game is short (about 1 minute?) and it's not likely that someone will want to replay it, but at least you enjoyed making it and learned something new.
On a side note, why does this game require 350MB of HDD memory...?
