i have played (and rated your game) the graphics looked good and there arent a lot of people here that submmited a game thats related to the theme so thank you for at least adding rain.
there were some small bugs:
the character it self rotates in delay from the camera (or it was a feature it looked like half feature and half bug)
and i could go throught walls if i tried pretty hard. i dont know how you coded the movement but by how it looked you didnt move the player in the script using a rigidbody and if i am right go on youtube and check for movement toturial and in the most of them they will show how to make a movement using rigidbody and it will probaly fix your problem .
if you want to i would be happy if you will play and rate my game.
