Thank you so much! We really poured our love for the genre into this one!
The ladders are quite difficult to spot! We've got a newer build that, I'll release after the contest, that has improved visibility for the ladders and makes the dragon a BIT more fair.
Currently, it does have a pattern. Any of the center windows will hit horizontally. Anything in the towers hits vertically.
This is still super confusing though, and I didn't notice the pattern one of our coders put in, so in the newer version we've improved this a lot!
