Minor update to add some small changes based on feedback I received for version 0.3.0.

Changelog:

• Level 9: changed the interactive double doors below to a fixed broken version to eliminate an unplanned way to finish the level more easily than I wanted.
• Level 13: moved the walking turrets' start position a little ahead so people replaying/speedrunning the level don't have to wait so long for them to get to a safe position.
• Disabled climbing while reloading weapons.
