It would be nice if your current score was displayed, seeing that cash on hand is not the same as your current score. This made the hard badge a bit more difficult to track. I had to kill myself to find out what my true score was. At least it was 42k and not less than 30k.
For those of you having trouble with level 45: Take all the neutral barracks on your side. Make few to little upgrades and concentrate all your forces in the fort. You will lose a few from having too many forces in the fort, but keep accumulating them until you have 450+. Launch everyone from the fort to the enemy barracks. The rest of the plan is simple after this.
The benefits of this plan are that you 1. keep your forces well protected until it is time to launch and 2. none of your barracks reach maximum population before launch time. Make sure to funnel troops from the more isolated barracks through allied territory to reduce losses until you have a large number of troops.
It only gives you reaction landings if you use the up arrow rather than the space bar! I spent a long time using the space bar and it wasn't working. The hard badge is MUCH easier knowing this.
I like how you can earn a lot at the deepest depths simply by salvaging the dead fish that come from the other fish fighting. You can be a pacifist and still collect fish!
