For six bucks this game feels a bit like a steal.
It has a good amount of world content, though some rooms and challenges feel aimless.
The game has less dialogue and lore than a SNES game.
The graphics are in a pleasant N64 style with options to make it more pixelated, as well as making animations more or less smooth.
The most important part are how the controls feels in this movement-heavy game and they feel very fluid and fast.
The game most certainly has combat. Can confirm. Yes.
The worst part of this Metroidvania game is that it does not have a map.
I finished this game in six hours, with a solid hour (or more) of desperately navigating places.

This game offers the following:

• Little, yet great voice acting
• Intriguing detective gameplay
• A serviceable, mysterious story
• Occasional eye strain due to the graphics
• A gradual understanding of sailing vessels
• Slowly-manifesting madness as you roam the ghost ship,
