this is cool

Thanks. Then I've misunderstood the content on the link, I assume due to other comments there. I've thought you've made some small working demake of the game, and I was really eager to try it out.

I love combination of pixels and symbols you've used here, very ballanced. I've tried to play with some similar editor once but gave up due to lack of time.

I use VICE! For making the piece, I used Marq's PETSCII.
The prg is a static image, so it's normal that no input is detected. You have to reset or switch on/off the C64 to do anything else.

This is so sick!

Can you please give some advices on the emulator? I really want to try it out, but few emulators failed me. They run the file but they somehow don't detect any kind of input from my side.

Excellent work! Just my take, I much prefer this one over the 'official' version, it has more character; although perhaps I'm somewhat bias as I've been dabbling in petscii lately (I had no idea it would be so addictive)
