I didn't see any game breaking bugs/errors, but here's a couple things I've noticed while playing for about 15 minutes. When I get the chance, I can go through the game more and see if I find anything else.
(I've been a game tester for a very long time and tend to find things that a lot of people might miss. Don't feel overwhelmed if I find a lot of bugs, since many of them would only be minor problems.)

You can't move diagonally if you press multiple movement keys at the same time. example w+a or s+d.
When you reach the area where the emergency broadcast starts, there is a "half" crate on the left.
If you have a wooden board or possibly other items in your "active" quick slot, you can't attack. If you have a soda or candybar in the active slot, you can accidentally use it instead of attacking.
When you reach the area with the knife, the FPS drops from 60 to around 30 and your character walks very slowly. This is most likely caused by the lighting or other items in the area. Once you go outside, the FPS at 60 again.
If you forget to break any crates or pick up the knife before going outside, you can't get them since you can't go back into the subway.
Stamina starts at 100/100. if you continue sprinting or attacking (possibly holding both buttons down) once it reaches 0/100, the second number will very slowly start to drop. I noticed it at 3/98.
(While in the subway) If your stamina is at 0 you can still attack. You can't sprint when it is at 0, but if you keep holding the button down you will speed up once in a while. This might only happen because of the FPS dropping at certain spots.
Candybar drops your maximum health by 3. it showed 97/97 after it was eaten. (This was when the character is at maximum health and still in the subway. I didn't check if it happens outside yet.)
If your character is "bumping" against a crate, go into your inventory. the inventory screen will slowly "bump" downwards. (picture included)
