Hi ! I know your game (nice game btw) :)
By tixy I suppose you mean https://tixy.land/ ? I have an idea, I'm currently not using the , operator so I could run the whole script each frame of an animation and the , operator would set the current cell at the frame id (modulo 256) and that way you could make animations.
Or if I want someting more like tixy I could set it to give the 4 variables, one at a time and looping. There are many possibilities for animation when I think of it.
After that I think I could add more operators but I think I like the simplicity of brainfuck so I'm unsure I'll do that.
Thanks for you feedback. I don't know what picture could serve as a thumbnail but I'll think of it !
