I am not a huge fan of plataform/metroidvania, but I tried anyway. After some minutes, I completly forgot about it.
It was so fun to explore. Sometimes I though that I was going to a completly different path that I was "suposed" to, but your game design was guiding me quietly. The player moviment is so precise and the blood preassure mechanic is fun to even look.
I didn't finished yet, but I'll be back to study for my future games or just to have some fun
EDIT: nice beginning animation btw
