Cool idea, the link to the theme is awesome. However, I couldn't get past the first stage like the other person. Do I not understand the game? IDK! If you were to build on this on the future though, I'm quite excited to see it :)
Thank you for playing and posting a screenshot! You completely understand the game, we just made the sucess criteria too strict. Lesson learned. This was our inteneded solution
We set the threshold for the boat/water overlap too high (or rather the sail had to be on water too which makes no sense).
