The paint tool doesn’t work please fix it

It won’t let me place agents

Response from developer

Thank you for your feedback. The fix is already done and waits for review!

Tesselations screen grab?

I get the impression the whole image area tiles the plane if I’m correct I don’t see an easy way to get a screen grab without all the little icons??? that would be a great new feature? unless it’s a quadruple tap or something.

Response from developer

Hi! Thank you for your request. Now you can only minimize these menus, but you’ll still have bottom icons. I’ll put the feature to my priority list

Absolutely cinema

Thanks!
