Hi. I played your game and recorded it on a video. It was very entertaining, and I was very engaged. It reminds me of such games as assassins creed four and classic gothic. They are my favorite games. :D I love the idea and sandbox parts. Here are the answers to the feedback questions:
1. I felt connected to the captain and the mention servant.
2. I felt like the sandbox could be very fun and big. Gothic games did not have a vast amount of items. However, each thing I could find felt very rare and useful. I could feel mightily rewarded.
3. The combat was easy but satisfying enough to not to bother about it. I felt powerful.
4. I enjoyed sailing. I like such a gameplay. Sadly, Such sailing gameplay sandboxes are not very popular now.
5. I am not rich, and I may not have enough time to buy and play all the released games nowadays. However, if the game had more immersive physics, I would spare 10 euros to purchase it.
If you want me to delete the video, let me know. However, if you like the video, I make similar videos every day. I will be happy if you subscribe. Anyway, I enjoyed playing your game.
