After a long time with no updates, here is the biggest update so far, even if there aren't as many new things.
Changes and new features:
Using proper semantic versioning from now on starting with this version 0.1.0.
Remade all user interfaces (Menus, Level selection, in game UI, etc) to look nicer, more unified and have better animations.
New better replay system for uploading and downloading world record replays automatically.
More efficient multiplayer that uses way less bandwidth for the same result.
A lot of rewrites of almost all major game systems that aren't as noticeable from the outside. Just so I can actually continue working on this project without going insane.
Removed German localization (now only English).
Many other small fixes.
With the rewrite of these core system I now can create new levels, cosmetics, challenges etc way more easily, but I might also have broken some things, so if you find any bugs please report them!
