after all the techs are done and all puzzles are done what else is there?

There is still the collectables left.

And that which confirms that you have esteem elders (hope this is ok to write without being a spoiler).

you could always change the difficulty setting and challenge yourself with a new village.

I am only missing one _bug_. can't seem to get it. only have one totem though

It may take time to get all the collectables. It took me forever, but I got them in the end. Be patient, there is a reward for getting all collectables. And you can have more totems than one...Take a look at the statistics. There you can see that the elders are counted. A hint that you can have more than one. And there are also different stews to find...
