During my playthrough, I got quite lost. I realized after starting the game again, "after beating it," that it was because I hadn't gone to the first area right in front of me. This confusion stemmed from experimenting with the controls and then losing track of where I started after moving the boat around.
In the early part of the game, I was traveling from location to location without having the necessary artifact item, which left me unsure of how to progress. I randomly discovered the first area I had missed some time later.
After collecting the artifact, I was able to proceed with the game as intended. However, once I had found everything else, I encountered the same issue again: I couldn’t locate the original area needed to complete the game.
Since this area features a lighthouse, it might be beneficial to illuminate the lighthouse as a beacon. This would make it much easier for players to locate. Additionally, it would be helpful to set the title screen to English by default. As an English speaker, I was initially unsure if I could play the game since I don't speak Portuguese. I do appreciate the inclusion of an English option, though.
I found the ending to be a bit lackluster and felt it could have been more engaging. In my opinion, a credits roll is always better than an automatic quit to the desktop, too.
Overall, I think it's a good game, and I don't mean to come across as if I didn't enjoy it because I did. I just believe it could use some more polish.
Edit: On the "Frigus" star, there is a typo in the line (I've "benn" observing stars simply stop talking)
