During the winter of 2018 I received some stuff from my childhood that had been stored at my partents' house. One of those things were my old Game Boy (the original from ca 1989). It didn't require too much to get it started, just some new batteries and then to insert and remove the cartridge a few times. Amazing!

Well, I had some time on my hands, so I decided that I wanted to make a game for the Game Boy, that I came to call "Tesla's Kitten".



You control a kitten that is ascending towards the sky, because of the balloons that have stuck to it. On the way you need to eat some butterflies to keep the kitten from going hungry.


The game is available for download here: Teslas_Kitten.zip.
You can use your favorite Game Boy emulator to run the game, or use a cartridge (e.g. an EverDrive-GB). I was using the BGB GameBoy emulator/debugger while developing and liked that one (BGB).
There are 2 versions of the game inside the ZIP archive. The only thing that differs is that the one named "SRAM" has been compiled for a cartridge with an MBC1 (a special chip on the cartridge), which allows for saving e.g. the high scores on a battery backed SRAM. The other version does not save the high scores between sessions.
This is the sticker for the cartridge. I am planning to order my game on a newly made cartridge and use this sticker.


I also made an "instruction booklet", just so that it would feel more like a real Game Boy game.
