Wonderful game! Very reminiscent of classic Nintendo era, especially of Ghouls and Goblins (at least for me). Controls were nice, responsive, and fluid! I do wish there were some form of health pickup. Right at the beginning being attacked right away by three of the shadow monsters feels a little much (my humble opinion). My other thought is, the boss skeleton may need a health bar just to know how close to beating it one is.
All in all, a really awesome game!!
