After a dozen or so tries, couldn't seem to get past the 9th lighthouse. I think I had the most issues with the flames, there's like 1 flame, you go down come up, extinguish it and by the time you're back there's already a new one. So it repeats like that and you can never seem to keep up with the lightning.
I did enjoy my time with it though and looked forward to reaching each lighthouse & meeting the characters, add an easy mode so I can see the ending :D. I really wanna see it, got really into the story but yeah, couldn't get past the 9th one.
I'm not sure if this intentional or not, but I did beat the 9th lighthouse, after that it was number 9 again. There's like two #9 lighthouses in a row. I thought it was on my end but looks like it's on other people's videos as well. Nice game, I really liked it!
