Such a nice little adventure. I loved the atmoshpere, the visuals, sounds and the all the cool little effects like the parallax or the foreground smoke. The combat also felt really good. If the boss had just a tiny tweaks, this game would be a perfect jam game: the attack where it throws the balls from left to right or right to left is almost impossible to dodge without losing hp (at least for me), and making just 1 checkpoint in the middle of his hp would've been nice. Also I'm not sure if the "sword only damages on the edge" works... I'm almost certain it worked even if I hit the enemy point blank.
A really nice entry, you'll get in the top 10 for sure :)
