My fellow yokai enthusiast! As expected, I really enjoyed the look of your entry. The N64-like artstyle is well done and immediately pushes my nostalgia buttons (though the SSAO does detract from the look a bit). The enemies are great, including their animations. I loved the Kappa grabbing rocks from the ground, that was a nice touch. Though I felt the player's animations were a bit stiff and combat lacked impact.
Otherwise the game was intriguing, but the environments are way too big. I got very lost in the cave beyond the marsh. It was all long stretches of nothing that took forever to walk through. At some point I unlocked a shortcut to the first cave but I did not identify any other way forward, or any powerup to justify being here, so I went back to try other paths but it was just too tedious. (Also, there's no collisions on houses in the village, but you probably already know about it.)
I love 3D Zelda-likes so I will be curious to see where it's going if you chose to keep working on it after the jam ;)
