Hopefully that's enough info

I get the same error but it looks like it is with a dependency rather than the author's code:
nsf/termbox-go#174

The program works fine on cmd and powershell on Windows

[alyyousuf7]

Keeping the issue opened until the bug in termbox is fixed or we move to some other library.

Thanks @deanveloper for reporting the issue, and @dasper for helping me out :)
