We just launched Update v1.0.0.8 for Cozy Marbles
Here's what's new:
New Track Pieces

We added 3 new track pieces:
Vertical Speed Booster
Flat Wide (4x4)
Flat Medium (2x2)
Quality-Of-Live Improvements
Option to hide Marble Names in Races

We added a Toggle so you can hide marble names during a race.
Move Objects up and down with the Arrow keys

Some players had problems holding Left Shift and moving the mouse to change object's heights, so we added alternative controls:
You can press and hold the Arrow keys or
click the new Up / Down buttons
Other improvements
Added longer interval settings (up to 15 seconds) to Marble Dispensers
Added a Button to hide Welcoming UI at the right side of the Main Menu.
Bugfixes
fixed a critical bug, where a game would not start properly when savegame files were corrupted. (If you saw the supporter pack UI at game start, but could not play, this should now be fixed).
fixed a bug where marble physics would be slowed down when setting Max FPS to 30.
Steam Achievements should now unlock better for some players.
