It's a .5 because it's NOT posted 1 day after the previous devlog.

We know that if you stop playing a level in a game, the next time you play it, you'll have to start over. It even happens with checkpoints, right?

Well, THAT won't happen in Inanimate Insanity Miracles!

You'll see a (or  if it's an online level) on a level if you played it before but stopped at a checkpoint.
The play button will be purple instead of green when you're about to play a level that has an icon seen above the line.
(Holding shift while clicking play or right-clicking the play button will make you start over instead of starting from last checkpoint)

And on the ghost recording of your run on a level with checkpoints, only the successful parts/attempts will count.
