v1.0.2 changes

Bug fixes:

• Adjusted the entrance to the maze in Level 3 so that you shouldn't get stuck (at least not nearly as easily) when trying to go up the stairs.

Changes:

• Added ability to press '1', '2', and '3' while on the Menu to load those scenes directly.
• Adjusted grass swaying intensity on level 1 to reduce nausea.
• Increased collider size/player height on level 1 and 2 to make it so that you more consistently collect the collectibles when walking over them. Note that the collectibles that are over the water are still intended to require jumping to collect.
