What is Baunsudaun?

Baunsudaun is a game developed in 2020 for the original Game Boy that is based on an old Java game.  See how long you can survive in Baunsudaun and compete for your personal best score.  In Baunsudaun you control 'Blob' by moving him left or right.  There are 7 different types of platforms that will spawn all with different effects.  Your goal is to not hit the spikes on the ceiling, or land on the fire at the bottom by trying to use the platforms to keep Blob alive as long as possible.  While all this is going on, the lines will continually move faster making it more difficult the higher your score gets.

Technical Details

Baunsudaun is an original Game Boy game that runs on actual hardware or emulators built to emulate the Game Boy hardware.  In order to play the game (.gb file), you will need a Game Boy flashcart (Everdrive, EZ Flash, etc), or a Game Boy emulator of your choice.  Please note I haven't tested all flastcarts or emulators so some might have issues.  Optionally if you're more technically inclined you can flash the game to your own Game Boy cart.

Immediately playable and enjoyable. Definitely one a "one more try" kind of game.

Did you use C or ASM to make it?

Thanks I used C with GBDK2020

Simple concept, yet fiendishly addictive! It's a great pick-up-and-play game that suits the platform nicely. Well done!

Thanks.  I love your work too!  It's leaps and bounds above what I can do.

If your game is 32kb or less, go on Catskull Electronics' 32kb cart and select Custom ROM. It's really cheap and works effectively.

It's 64kb.  I couldn't keep it to 32kb because background animations and the song put it over.

Look around a bit, there are a few with more storage somewhere on the internet. I'd love to see it on a real gameboy!

it will fit on one of the Chinese bootleg carts from aliexpress that’s what I used to create a short run of my game

Maybe down the road it would be cool to make some carts.  I'm still waiting on my GB flashcart I ordered months ago lol.  Also thanks again for your tutorials.  They helped a lot with this game!
