We are pleased to announce that a limited-time collaboration with "DEBUG NEPHEMEE" has started today, running from November 5 to December 18.

"DEBUG NEPHEMEE" is an adventure game in which you "debug" a bug-infested world inhabited by creatures called "Nephemee."
Like Sill Cats, it features pixel-art characters, but unlike Sill Cats, it's a game that really makes you use your head.
A free demo of DEBUG NEPHEMEE is available. You can jump to the DEBUG NEPHEMEE store page from the cat signboard's settings screen, so please give it a try!
When you get tired from DEBUG NEPHEMEE, take a break by watching Sill Cats.
