Post game jam update

Post Game Jam update to the game

I went through the feedback we got, and have made some quality of life changes based on it:

• Increased movement speed
• Tightened collision boxes for most interactable things, to make it feel more smooth
• Added an animation to push
• Fixed one of the maps where you had to shimmy a box to solve the puzzle the intended way
• Made it so that boxes only can move in one direction at a time, removing shimmy
