Timeline going "reverse" and disabling my character controls

Hey guys,
i'm trying to learn how to use Timeline and i'm having a really weird interaction.

When i created and animated my gameobjects everything went fine, even in the Scene preview the Timeline is great, but when i simulate the game the Timeline is acting on her own.

Here is the Timeline in the scene tab : https://gyazo.com/e16c65d2be8207ffa9f3346183955ede

Here is the Timeline in the game tab : https://gyazo.com/696eda8bb95a1d3dca7cd278fe258ce7

As you can see in the game tab i can't move using WASD, which is fine, but the rotation is controlled by my mouse movement, which should only happen once the timeline ends.
But what happens at the end is that the camera doesn't change, and I'm still not able to move using WASD nor any movement key or joypad.

Hope you can help me and have a nice day !
