One way to not needing to have tutorials is to make it more obvious what items do and how. The keycard in the office you need to click the mouse to use to open the door. The lock is not the same color or shape as you would expect a keycard to fit through. The colors of the text above the doors does not correspond to the color of the key you need to have to open them. These things confuses the player. Also the jump ability is a keycard  and has same color as a door key card which mixes it up even further. The collider I remember where it was was on top of the broken ladder at the main area which you are not supposed to be able to climb I guess, but you pass into the structure. Hope this helps! And once again good job!
