One of yoru best!
This is a great game, but the weirdest thing is that I get medals even though they don't show up on the author's comments. The music is great and it creates a wonderful atmosphere. I especially like the notion that this little kid is so pathetic. I didn't know the Biblical story of Isaac took place in modern times. Of course, I'm looking too deep into something that should just be pure fun. I got used to the controls pretty easily. I just love how this character has so much mobility to go everywhere.
Everytime you die, you seem to get a different set of levels to go to. It's great how everything is truly unpredictable. I have played a lot of your games before, but none that I was willing to give a 10/10 to! Call me a fan of yours from now on. The enemies are designed wonderfully as well, especially the boss that keeps turning into tinier versions of itself. Even the way the medals flash on screen is cool!
