What Friends Are For received first place in Game Boy Showdown 2023! Thank you for your support!

What Friends Are For is a puzzle platformer for the original Game Boy. It was developed in GB Studio for Game Boy Showdown 2023. Switch between friendly and unfriendly modes to use your enemies to solve puzzles and platforming challenges... or are they your friends? The game features 5 unique levels lovingly made in a week by Shin, with an awesome dynamic soundtrack from Beatscribe.

What Friends Are For V2.0 is now available! Featuring Game Boy Color compatibility, improved performance and better accessibility, V2.0 adds a coat of polish while keeping the original game intact. If you want to play the original jam version, it is still available to download below.

Install instructions

Run the .gb file in the emulator of your choice, or upload to any flashcart to run on hardware. Playing on Game Boy Color or an emulator in Color mode will significantly increase performance and eliminate slowdown. If you are playing on emulator, I recommend the BGB emulator. If you are playing on hardware, the .gb file is 256KB and uses saves, so make sure you are using the appropriate flashcart.

Great game, what an awesome concept. Love the design, art, music and controls. Really enjoyed playing it!... Until this point }:(

Must have tried a good 30+ times and  just gotta give up now, unfortunately. Can't figure it out, that or I have and just can't get the timing right. Would have been nice to see the end of the game.

Congrats on winning, well deserved!
