Guide your bouncing balls around obstacles or try to avoid them at all. There are really plenty of levels, which makes this game outstanding. Coded by HuCABBAGE for GB Jam 4.

Real Game Boy games are a challenge to code, not only you have to deal with restriction such as low CPU power, also the limited color scale (if you can talk about colors at these grey scales at all) is distracting new coders to get familiar with this system.

HuCABBAGE is one of the newer homebrew coders who picked up the challenge and the result is The Bouncing Ball, initially released for the GB Jam 4.

Guide your bouncing balls around obstacles or try to avoid them at all. There are really plenty of levels, which makes this game outstanding.

Gunman Clive is a game by Bertil Hörberg which is available for money on Nintendo Wii U,
Nintendo 3DS, Steam, iOS and Android. To possibly promote these systems Bertil goes a few steps back, especially into a time, when he was famous for Game Boy homebrew and releases a playable one level demo of Gunman Clive for the Game Boy itself! Too bad it only got one level… but who knows, maybe the game could grow into something larger?

Thanks to ph0x for the news!
