Heyy, It's a very cozy game:D Maybe a bit slow for my liking but extremely polished overall. 
It felt like the endgame is mostly boats that don't fit the rules, it might have been because the rules were random. Some of the rules could be explained in-game. I was second guessing myself on some of the expressions. I would imagine a lot of the players wouldn't have experience with programming syntax - unary and binary operators. This must have taken quite a bit of time to get to the current balance :D Great game!
