10mg: You are such a Soft and Round Kitten.
A free web version is available.

There are no significant differences between the downloadable version and the web version. The reason the downloadable version is not free is because:
1. To make a Steam game free, I have to manually contact Steam Support and ask them to make it free.
2. The game is part of the 10mg Bundle and I don't know how making it free would affect the bundle.
I do not recommend purchasing the downloadable version unless you want to support me by giving me money, or if you really want this game to appear in your Steam library.
Corn
It seems Corn has been added to the game.
This useful item will make it easier to navigate the hellish labyrinth of doors without getting lost.
If you couldn't finish the game, try again with Corn.
