Great game with a few diffrent strategies to try.
Some problems/bugs.
1: Ship weapons sometimes vanish and never come back. I've been well into the game and then lost because the ship was defenseless.
2: The bomber units that sit at the bottom of the screen and spam mines. These get a little annoying as they deal tons of damage over time. Maybe shorten the firing rate or slow the speed of the mines rising?
3: The other Mermen seem to never fire their missiles or vulcans?
ME.
Did anyone else get a blackscreen? The game isn't starting.. -_-
I love this game but the Vulcan is useless and the sniper rifle is a bit weak. I suggest you lower the sniper rifle ammo and raise the damage. For the Vulcan, increase its ammo, range, and bullet speed. The music also stops playing sometimes. The AI mermen should also try moving more often when fighting. Those are only minor issues and they don't get in the way of the game play that much so give this game a try.
Awesome game, but its way too easy. Just focus on upgrading the atlantis turrets (speed and damage) and you win.
