Very fun, I'm into pirates and upgrade games, the graphics are okay and the voice acting is quite funny. I would have given it 5 stars if not for some reasons: no mute button, really? the music is fine but if I wanna do something else without exiting the game it'really annoying. And another thing I paused when I made enough money for the cargo upgrade and the money I collected till then didn't save so that was a bit frustrating. Also lots of times icebergs and spikes appeared right in front of my ships so there isn't any way to destroy them before it destroys the ship (or was that intentional to add to the challenge? xD)
Anyway I really enjoyed the game.
