concept is good, but fights take waaaaay too long. I'm on first one now and it's taking about 10 minutes just to kill one guy and it's really annoying. The graphics are kind of bad as well.
@WeaselCorp: it actually shows you where the cloaked units are if they move, and they make a noise as well, but on chapter 8 the AI waits for about 5 mins doing nothing after moving all if its units. Cloaked ones as well.
some levels are so annoying: youy get through to the last wave and they send 6 orange zeppelins followed by another wave of 8 zeppelins followed by about 15 smaller balloons. Really wastes your time.
