A few years ago I worked in a project to do a new tamagotchi. The idea was the the monster was going to be generated using random algorithm and work as an nft.

I never got to finish the project, partially because o the hate for NFTs, but there where a few functions I got to implement, like playing jan ken po with your virtual pet, and was about to finish implementing playing in a network with other virtual pets.

I made a video of random animation tests in the beginning of the project https://www.youtube.com/watch?v=fltoTmUJPBE
