Basic tactic on any level:
Build a huge mountain with a small flat surface on top. Wait for some of your guys to settle there. Flood a couple times. Win. Repeat for each level. Very boring.
After progressing further into this game, I noticed the bizarre spelling and grammar issues with this game. It has obviously been translated from another language, would have been 4/5, now 2/5.
Ehem... Someone is a retard. All those accounts which have posted so far come from the same ip, all but one is a level one account, and for me the game doesn't load. 1/5, flagged.
Ha ha ha nice easter egg: Along the bottom of the ocean near the right hand side of the screen is a pineapple house! Who lives in a pineapple under the sea? Rate + to keep this at the top.
