As a fan of the whole pirate aesthetic and rhythm games, this is a fun demo, and a nice twist on an adventure RPG. The concept is inventive, the dialogue is witty, and the mechanics are taught in a way that feels natural. Looking forward to the full game.
If I had one criticism, the in-game font is really hard to read. This is a 160x144 screen, after all. The splash screen has a more readable font, so please consider at least having an option to switch to that one.
And I’ve never used GB Studio before, so I don’t know how hard these are to implement, but I also encourage QOL improvements like diagonal movement and using stairs from any side.
