Let's be honest, the game looked dull and it had no depth before. With minimalism still the core behind the game's art, find yourself engaging more with improved art. There are other fixes too, but mainly, the game looks better now.
If you still need to know about what the fixes are:
In-level walls now correctly interact with the player.
Death and collecting the last World Piece no longer occurs at the same time. Death occurs first.
Demo builds will not hold actual game-data, and vice versa.
Fixed not all collectibles being collected in certain scenarios.
Fixed collision issues after a Fragment reset.
Added a setting to show buttons for player movement simulation queue.
Optimizations (these are too technical, won't go into that here).
Demo and Release Timelines are now correctly packed into the relevant builds.
Fear not, this is not the last of the art updates you'll see.
