Took me a second to figure out what was going on but I enjoyed it and beat it. The minimap is clutch. I didn't realize that was the boss the first time I faced off, perhaps label it like the other elements of the game? I noticed it was labeled in the minimap on second play. Enjoyable and fun experience.
Cool font as well! Though it looks like you're missing a few of the characters. Great use of the theme as well I liked that! Good job all!
