Demo Hotfix 1.1.3

There were still a few bugs in the last hotfix, these should all be fixed now. Please let me know if there are any issues with this hotfix as I have made some more significant changes (compared to the last hotfix).

Here's the full list of changes for 1.1.3:

• Fixed another Map 4 bug with enemy hitboxes. Enemies now have separate hitboxes for checking if they've been shot, which I've made slightly bigger
  
• Updated the hedge "walls" on Map 3. They are larger now and it should be more obvious that they are actual walls, not just invisible walls
  
• Updated and expanded the secret mechanics. This is an internal change for now, so it shouldn't affect how the current secrets work, but should allow me to create more interesting secrets for future levels. Please let me know if you encounter any bugs with this
