This is a great game! I can see that a lot of work went into this and it looks and plays really well! It’s a shame that there are only two ratings so far, I hope you will get more people to play it.
One thing that might help: The “you can’t go back” rule is an interesting mechanic, but I had to read the p.s. on the game page to find it. I was confused since I kept losing without running out of courage. It also makes you lose fast sometimes because you don’t know that the next step will not reveal new adjecent islands, so how do you know not to do the step(please correct me if I’m wrong)? Maybe you could outline the edges of the world?
Nice interpretation of the theme and cool idea to fulfill the limitation. Good job!
