Quick bugfix after feedback

After officially releasing the public demo for Pouchie, I let my friends play test the game and give me some feedback on improving the game. The following bugfixes were implemented after listening to said feedback and making some changes.

Bugfixes:

• Added controlled jumps. Player can now jump higher or lower depending on how long they hold down the jump button.
• Added new keyboard options for running and jumping (Z for running, X for jumping).
• Getting hit by Bootstrapper mobs will now grant two seconds of invincibility, where the mobs will no longer be harmful. The player will however still collide with the mobs, so trying to pass through them is not currently possible, nor recommended.
• Increased walk and run speed for a more dynamic gameplay.
• Improved camera functionality so that the camera will lower back down to the ground more.
• Increased deceleration when walking so that the character doesn't slide too far after the player released the controls
