Added Bug Fixes and 2D Lighting engine

Just fixed up some of the issues that came along with the crunch of the 2025 Toronto Game Jam.
So with a proper night's sleep and some time away from the computer, we've returned and fixed some major issues.

• Fixed some major bugs with loading between levels and resetting after the player dies.
• Resolved some level design errors where Walls were mistaken placed in the wrong grid space, leading to issues where walls would burn down like the wheat fields.
• Fixed Menu bugs.

Additionally, we've added in some 2D lighting to add some better ambience to the scene and improved the post processing on the fire and screen effects. Let us know how these changes affect performance.
