That was fun. I wasn’t able to finish it, I started pressing buttons to see if that triggered any achievements and the “X” stopped (crashed?) the game. If it does stop the game, a confirmation dialog would have been nice.
I was about 30 gold short of talking with the duck and didn’t see any other bags of gold to progress, but I could have missed them.
Overall, I liked it. Once you update it I’d like to give it another go to see how it ends.
