To be able to help you, we need to have access to the project, not the exported game. Save your .c3p file to an online hosting platform like dropbox or google drive, make it sharable and past the link into a forum post. Then we can download the project, open it in Construct and see what is going on.
I noticed playing your game that the players origin is messed up so when you turn around the sprite changes position. It is so off that if you walk next to a wall and try to turn around, you wind up in the wall and can't move. This only happens when using wasd, not the arrow keys. The arrow keys don't turn the character, they just move it.
