0.33 - Improving Switches tutorials

Two of the Switches tutorials have been improved based on playtester feedback:

• Switches I now introduces the concept of doors that boulders can pass through but the player cannot. These are used extensively in harder levels and now have the introduction they deserve
• Switches III now teaches the player that wall buttons can still be pressed even when an object is directly in front of them. Again, this is used later on in harder puzzles and was missing an introduction
• Switches III’s middle puzzles have been modified to be simpler and impossible to cheat like they were before

In addition, level doors now indicate the status of the level to improve readability:

• Locked levels have a padlock indicator on their door’s action prompt
• Beaten levels have green lights outside their door
