Loved the concept! I played it through a few times but never could win :P
I died to scurvy a lot, it didn't feel like I could have saved myself. After a couple of games, I started popping the barrels as fast as I could from half scurvy onwards and still didn't get any lemons :( maybe having a lemon barrel that's further from the action but was guaranteed to have lemons would make it less randomly punishing, and still keeps your fun random barrels?
Your use of the theme was hilarious! I liked the very Sea of Thieves cannon launch haha
