YAS (Yet Another Snake) is a Snake/Nibbles-like game for CHIP-8, coded in 2015 and bundled with CHIP-OTTO, my CHIP-8 virtual machine/interpreter. Now it is also available on retrobits.itch.io, both for online play and for download. The web browser version is powered by the Octo interpreter; if it doesn’t work in your browser, you can try with WEB-OTTO, the HTML5 port of my virtual machine.
Enjoy!
