A big update focused on making online play smooth and fixing a bunch of things.

🌐 Multiplayer
- Online play is now **much smoother** — players move fluidly instead of stuttering.
- Moving platforms and physics objects now **work correctly for everyone**. No more objects sitting frozen for other players.
- Falling objects (the cubes) now behave **consistently for all players** in a session — what the host sees is what everyone sees.
- More reliable connections between players in a lobby.
- Added a **ping / connection indicator** so you can see your online connection quality.

⚡ Performance & Visuals
- Lighter default rendering for **better performance**.
- **Sharper text and UI** on high-resolution (hi-DPI) displays.
- Music now loads instantly and no longer causes **hitches or stutters** mid-game.

✨ Quality of Life
- The intro cutscene now **plays only once** — no more sitting through it every time you restart.
- Added a **tutorial hint for first-time players** and **clearer difficulty names**.
- **Tighter, more responsive controller controls** (reduced stick dead zone).

🐛 Bug Fixes
- Achievements now **save reliably** between sessions.
- Fixed the "5 hours played" achievement triggering incorrectly.
- Fixed crashes/issues when **Discord isn't running**.
- Fixed issues with Steam DLC checks when Steam wasn't fully ready.
