You can share it in “play mode” 
In the Share menu, just select Can view 
And then, go to Embed and check if Enable Play is toggled On .
This will allow others to literally play with your doc but their actions won’t be saved .
All, you would need to do then is to click on Copy Embed and paste it in your post/topic .
Hope this helps
Pretty cool doc by the way 
!
(I’ll take a better look at it when I have a little bit more time )
