Orb Catcher is a game by Patrick Rodriguez/Patchwork Games.

You can roll back up by touching a ball winder or by backtracking your steps. You cannot roll over previously laid yarn (i.e. cross your own path). Goals and winders are only activated if touched using your last piece of yarn. You can see how much yarn you have left on the bottom of the screen. The number on the bottom right of the screen is the level number. There are 23 levels total. Can you solve them all?

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.

Steins Gate is a clone/remake of the 8-bit sequel to the Steins Gate anime/visual novel. Coded by calc84maniac. Even though it’s a non-canon spin-off, it does contain major spoilers for the original Steins Gate story. It might not make sense unless you’ve watched/played Steins Gate.
