This is such an insanely fun game with an insanely killer atmosphere! I love the crumbling castles and unique enemies. The platforming is so tight and the amount of freedom you have to explore around the way you wish is great. Early on, you feel like you're wandering aimlessly, but as you explore more and circle back, you start to form a kind of mental map in your head of the general location of some rooms. I love how you can get around puzzles and rooms, many times without the "intended" power up, just with the powerups on hand and your own skill. It's so cathartic. The final boss fight is also a joy to fight. I love this game!
