v0.2.0 Double update! New levels, gameplay and balance changes, level editor

Hey there!
Due to circumstances out of our control, the previous update had to be delayed to the point where we decided to just merge it with this one instead. Our apologies for taking so long. This update hits a major milestone of Nebula Flow's early access: custom level support!

Changelog:

• Refined the gameplay and balanced the difficulty accordingly.
  The game is now more accessible to new players and provides a better experience overall.
  The "How to play" menu and tutorial have been updated to reflect these changes.
• Added three new levels following "Sun-kissed".
• Added a level editor and custom level support. Everything is wrapped up in a fancy new "Custom levels" menu.
  Full documentation is provided in the editor's help menu.
• Profiles can now be named.
• A few cosmetic and QoL changes.
• Fixed rare bug where a note could not be hit the next frame after hitting a move.
• Some performance improvements.
• Fixed a few minor bugs.

For the next major update, we will focus on achievements and Steam workshop integration for custom levels.
Thank you for supporting us, we hope you'll enjoy what we've been cooking up.
