WIP 0075 - Unlock scene system, sound effects (Patreon)

It was a bit tedious this time. I implemented a function to unlock reward scenes through packets obtained from the game. When you kill enemies in the game, you gain experience points or packets. The structure is to unlock various scenes and suits through the obtained packets. I also plan to create scenes that require certain drop items to be unlocked.

And I changed the sound effect and UI structure a little. I had a really hard time because there were a lot of things that didn't work. 😫
