@keks321 regarding points.
the best i've done is somewhere around 3k. the key for a lot of points is shooting goals, i believe.
upgrade tip: speed is way more important than power
tip: 's' and 'e' should be upgraded. i also use a lot 'ing'.
the game accepts most flexions, so its clever to go for the common affixes (lak-es, sensor-s, sens-ing, sens-ed).
about the dictionary:
country names like 'America' and most compounds are not valid.
this is easily understandable because the search space would get too large (millions of named entities!). also compounds are principally of infinite number.
imho, the dictionary already is brilliant.
