Thanks for the Fix. Now it works fine on my PC.

One suggestion:
In my opinion it would be good if you add a restart key (for example R) to restart a level, so that you don't have to go to the menue and select restart. This would be more efficient if you messed up in a level and are not being destroyed.

I am going to be honest, some people will find certain puzzles in this game annoying (especially later ones), as Constant C is not a game for everyone. But the 'Ah-ha' moment that you finally figure it out is extremely satisfying. This game also have a strong story arc, though not in the foreground. But piece together the mysterious events that happened while struggling to understand the physics and time mechanics just adds more flavors on to each part. Graphic is not astonishing or artistically…
