It's just square dots and lines of your choice of color. Are there any options or ways to get it to show the event's text in the month view as it does in the week/agenda/etc?

Apparently month view was stripped out of the latest store version. I don't understand how a calendar could be better without the ability to see the whole month (or at least the option to) as you would on a wall but so be it.
Jorte Calendar is a free alternative that offers this functionality. It also synchronizes with Google calendar both ways.
It looks normal by default and the icons only get added if you want them there.
Google Calendar doesn't have that feature.
You can use a 3rd party app like aCalendar instead (paid/free).
That isn't an option in the Google Calendar app. However, you could:
Note that all the features might not work depending on the browser, but Chrome Mobile seems to do pretty well.
On 23 April 2015, Google Calendar was updated with the return on Month view.

On top of that, the current version also displays the event name instead of square dots and lines.
Note, however, that it only works on portrait mode. The landscape mode only displays in Week view.
