Hey lewdev - yeah, I am indeed that masa (small world!). Good to hear from you.
Thanks for the feedback - the scoring system was a hurried effort to create a bit of gameplay, so yeah, definitely there's more scope to improve, and your idea about rewarding prompt actions make a lot of sense.
Also thanks for the heads up about the github link - I forgot to make the repo public. I've updated the setting so it should now be visible
