The environment and levels are gorgeous. I very much enjoyed the cinematic effects. The gameplay, and specifically the character controls, were a bit confusing to me and I had a few issues with the physics. I felt like I didn't have enough control of the character and the anticipation phase of enemies' attacks were a bit sudden. Despite of that, I think with a few numeric adjustments and some extra visual feedback, those issues would definitely go away.
One thing that was really nice was the indication from enemies as to where to defend and how to attack. I died lots of times at the beginning but when it finally clicked, it made a lot of sense and I started having a lot of fun. Also, the environmental attacks with the fire and all were a great touch.
This game is full of very interesting details. The butterflies, the blood mechanics, the crustacean boss, the ending, the pretty environment. I feel like this has lots of potential, good job!
