So much to say here I love it! First of all, I love how the main menu is actually part of the first section of the game, such an awesome transition. I love how the light mechanic is flipped on its head once you play as the shadow - really innovative!
My only gripe (and it's reaaaally minor don't worry lol) is that I felt the game could have benefitted from having a light source that healed the health of the human form. You only find out about the mechanic by taking damage, which by that point it made it impossible for me to win without retrying. Like I said, very minor point lol
Very impressive! I love this game!
