The game has some not so great aspects:
There are only 5 levels. If you beat 4, the last one is simple, unless the game glitches, which it does. I’m currently hovered over the entire shielded city, with its 2 islands inside my ship, but I can’t attack anything, and no one can attack me, no matter where I move.
The dynamite chests don’t cause any damage to anyone.
Even as your raft gets bigger, the ocean doesn’t.
If you don’t grab a lifelong magnet, you’re limited to how many people you can pick up from the water, which is fine until level 3 when the Boss has 400.
There’s no variety in the play area; no islands to navigate around, no edies or whirlpools, no land based enemies. It’s just a big rectangle.
Once you figure out to attack as many ships as possible and avoid the boss until you’ve collected every person and raft and treasure chest in the rectangle, you hit the boss and you’re done. It’s almost impossible to lose.
