As a fellow pirate-duel-themed-entry jammer, I've been keeping an eye on this one since I first saw the progress pics in the discord.
Besides a bug I found (where something, I think it's pressing a direction too soon, causes the wrong rebukes to show up for a given insult), some mild jank (like having to face upwards to talk to a pirate above despite not having an up sprite) and the obvious stuff (music/SFX), this met expectations!
Graphically, I love the palette choice, and the old PC game vibes, what with the big soft illustrations, boxy static sprites and a focus on wit more than anything actiony, even if it's not pure gameboy besides the limitations.
Also, "Your socks don't match" totally should've been a valid insult for the peg-legged captain!
