A small update to the Demo today

Based on feedback from enthusiastic players, I’ve made a small update to the Demo today.

The laser sword no longer requires equipment; it can be activated by pressing F while in the backpack.
Added storage boxes at two key locations.
Optimized and changed the number and location of some items.
Fixed the bug where the character's backpack would slide open when accessed.

Thank you for your support and feedback, and I hope you enjoy the game!
Please leave feedback or suggestions if you have any, and once again, thank you!
