Very atmospheric, really loved your artwork. Everything felt well thought out and put together. I particulary liked the shader for the shadow/hiding in bushes.
Big fan of stealth games too, loved that you didn't do too much explaining, that you just jumped right into it and let the player make their own conclusions. Also, i appreciated the little touch of forcing a player to walk through tall grass right at the beginning, to make them realise "Ahh, okay, i will probably need to hide in tall grass. "
Couldn't finish it unfortunatly though, there was one particular area i was struggling with for a few minutes before giving up, which is a shame! But i had a great time with it regardless.
Very fun game, you should be proud of it
