i think its very much cooler with multiplayer.
that you must build towers and attackers to win from the other one, i think its fun too with a warship...
it has a light shield and has 3 lasers, but it is very slow and must be very close to your base.
with all this 10/5, without 5/5.
steps to make REAL business:
day 1: make by the third from the left a pet store and before that shop a bench, then news, then bench.
day 2 or 3: make after the petshop a boutique.
day 4 or 5: upgrade boutique and make the line of benches so further bench, news, bench.
after that you can do what you want with it ;D
