I'm not sure if I understand your question. Can you please specify which step are you trying to run and what is the output you are seeing?

What environment is necessary to make this work? I tried various terminals, with varying results, but none of them will run this game (go-running the main.go from Step 9).

• go version go1.13.1 linux/amd64
• tried MATE Terminal (colourful, no movement, no player/ghosts), Sakura (similar), xvt (instant game over, no nice graphics), alacritty (flashes, no black & white graphics).

This is a minor fix to the README, or at least I think it is a fix unless the missing parameter was intentional :)

Thanks for spotting this! Definitely a mistake :)
