Took me a bit to get used to the gameplay, but I see the idea! I do feel like there are too many restrictions/things to do though, such as having to run down to the sails and back up to the steering wheel to move, and back down to stop.
A way to stop the ship from the steering wheel would be nice, because I often sail past the crewmates while trying to stop the ship. Maybe a way to heal too? While focusing on saving the crewmates, I'm unable to shoot down the enemy ships and take a lot of damage by the time I reach only one-third of the goal.
This game does have a lot potential though, with the different mechanics offered, and I did have fun playing! (before I eventually took too much damage orz) If you plan to develop this game further, I look forward to its growth!
