It's not my system -- I suggest posting in the reddit thread to reach the author.

How does your system respond to environmental effects. Eg: it's raining, it that wizard hidden behind the bar is counter spelling. It feels like you've spent all of the effort on the grammar, but there's no event loop.

If you are using Android and have an interest in RPN calculators, I highly recommend RpnCalc. No ads, no tracking, just a great calculator.
