Once I got it to launch, this was a lovely experience: short, sweet, and really doing a lot with very little. I love how you one-upped the whole minimalist aesthetic of the jam with the simple, but highly evocative, chalk art. The story is really sweet, too.
On Linux (Ubuntu 20.04), both the Linux and Windows default launchers fail, with the error “Error of failed request: BadLength (poly request too large or internal Xlib length error)”. However, by launching the .exe from the Itch.io desktop app, the game ran fine under Wine.
