I don't know when this game will be release on steam, but I REALLY hope it will be soon! o.o
I've played the demo damn! I really like it, it made me feel like I was ten years old again :D with my gameboy color.
I love the music. I'm a 3D character artist and usually I only look at more recent games for character creation and reference, but that jester made me laugh so much XD it's incredible how much a pixeled character gave me feel.
