up/down movement against collidable blocks disallows left/right movements

[goddtriffin]

When travelling upwards or downwards against a collidable terrain tile (ie. trees or stone), you cannot, at the same time, travel left or right along the collidable terrain tile.

To showcase bug live, keep pressing 'W' to move upwards and collide with a tree or stone, then when colliding, keep holding down 'W', and press at the same time 'A' or 'D' to attempt to move horizontally alongside the collidable terrain tile.

If this bug isn't fixed at the time of testing, this should not work (when it should).

This bug also works if you're pressing 'S' to travel downwards until you collide against a collidable terrain tile, and from there you just follow the rest of the steps to re-produce the bug.
