Hey thanks for the feedback!
First of all, i don't think Goya qualifies as a fan game, as we didn't use the real paintings but just Goya's style. All was painted and then digitalized by our artist.
About the feedback on the first boss, i agree that it is pretty difficult to know about the skulls. We tried explaining it using the goat, but i guess it was not enough (or it was badly explained). I think we could have improved this and the stiffness with more time. Even in a month we had little time to work on the actual game, sadly. So yeah, you are totally right. If i have time I'll make the attack a little bigger!
Again, thanks for your time. Have a nice day!
