Pretty unique pirate ship game that feels like you're sailing on the sea, and shooting down enemy pirate ships with your side cannons. I also like the loot mechanic that you can spend on upgrades after making deliveries, but it also serves as your health. It does get ridiculous when you spend gold on sail speed but it's also fun in that way.
The visuals are great but I think they could've felt more like a Game Boy game beyond the colour pallete.
I think the pop-ups menus could've been less distracting and actually pause the game so that you don't get hurt while deciding what to buy (the HP bar could've overlapped the upgrade menu).
Good job overall!
