Some things returned by getchar are not integers, apparently (e.g. <Left> and mouse clicks return a string rather than a single keycode). As such, string.char does not work on them, and it throws an error when you try to use it how it was being used before.
To fix it, I moved the string.char conversion into the pcall that already existed for getchar.
