A tidal wave, meant to be the second most powerful force in your possession, and all it does is kills you, and helps your enemies. Fail, game makers, EPIC FAIL
By the way, I've noticed how so many people hate the price of upgrades, and fighting the boss. The upgrades are fine, it takes one or two days to get one at the start, then gets easier and easier throughout the game. This game isn't meant to take 10 minutes to win! The upgrades aren't supposed to be cheap! Also, the boss is meant to be hard if you don't have a good ship. So upgrade your ship before fighting it, obviously! I beat the boss quite easily with a high upgraded ship. That's the point! I think this game is perfected.
This game has it all. Easy days at the beginning to learn how to control your ship, plenty of different quests to do, puzzles and strategy, upgrades for awesome weapons, large world to roam and destroy ships in, large supply of weapons for different strategies, enough upgrades to increase damage and armor to tank other ships (very fun to do after working hard for all those upgrades), and to top it all off, A PIRATE LAUNCHING CANNON!!!
