Demo Update v. 0.63

In this version, I decided to completely redesign the progression system.

Now, upon reaching a new level, the player can choose two perks at once — one daytime perk and one nighttime perk.

Other changes:

- During weapon reloads, you now see a progress bar showing the remaining reload time.

- The cost of using the slot machine now increases after each attempt.

- Shard pickup radius has been increased.

- Ongoing work on overall game balance.

- Bug fixes.
