Bug fixes and some QoL changes.

Made some changes to the Pick 'n' Pocket demo based off of some feedback.

• Pick and Pocket now move a little faster and jump a little higher. This should make the game feel a little more fast paced.
• Added some climbable pipes to the upper story of Cabin multiplayer level. This should give players more freedom to move around the map.
• Made some color changes to some tiles to help make them stand out a little more.
• Myriad of bug fixes. Please let me know if you find any!
