Played the html version since I don't have windows. It's a nice game. I didn't get to the boss initially but followed your spoiler. I don't feel that the boss adds much variation.
Thanks!! the html5 version can't be resized it's a bug that i can't fix, im happy that you still played on it, hhaha, yeaa, the boss is kinda just an optional route on playing the game. Thanks for the feedback !!
