Your game has absolutely stunning artwork. The swashbuckling also looks fantastic. I'm just not very good at it. Being bested by frogs and mice is kinda humiliating. ^^
Some of the enemies are hard to spot, as they blend in with the background/foreground occasionally. Their hitbox could also be a bit bigger, I reckon. It's hard to hit them without getting hurt. And I got hurt. A lot. These critters are relentless. :)
There is two more things I'd like to mention: Having to use the mouse for choosing things felt a bit clunky. Playing Blackjack with it was fine though. And you stand very close to the transition from one area to another when you restart. I've accidentally crossed over several times. It would be nice to be placed a little further away.
As mentioned, it's a beautiful game. Fun to play too. There is so much to explore! Good luck finishing the game. :)
