The jump strength could be buffed slightly. Movement and animations look good though. Environment looks nice. The main downside of this project is the combination between the full screen button not working, and the mouse not be constrained to the screen. This makes the camera movement super restrictive. Plus, since there is a crosshair, removing the mouse visibility could be a nice touch. Pause doesn't pause the game, and since you have a main menu, either a menu button, or quit taking you to the menu would make more sense.
